As a doting dog owner, you find yourself looking for the best dog multivitamins. But do dogs need them? And if so, which multivitamins are the best? If you are feeding your pooch a balanced and complete diet, there is usually no need for vitamin supplements for your dog. However, there are some cases where your vet will recommend starting a course of dog multivitamins.

There are several things to consider when choosing the best multivitamin for dogs. What works for one dog may not be suitable for another. So, it is important to take your vet’s advice and to consider your special pup’s needs. Your dog may prefer delicious chewable tablets or may need to be tricked into taking liquid multivitamins.

When do Dogs Need Multivitamins?

If your dog suffers from health or behavioral problems, make sure to ask your vet about potential vitamin deficiencies. Imbalanced homemade meals, poor quality dog food, parasitic infections, and conditions like anemia and diabetes can lead to vitamin deficiencies. In these cases, your vet may recommend multivitamins.

If your dog is given a complete and balanced diet, they most likely do not need a vitamin supplement. A complete diet should provide all of the vitamins and minerals that your dog needs to be healthy! If you are worried about your dog’s diet, you can always add some fresh and safe vegetables to your dog’s diet to give a natural boost of nutrition. Over-supplementing your furry friend with multivitamins can cause more harm than good!

What Vitamins do Dogs Need?

Like us, dogs need an array of vitamins to be happy and healthy. Most dogs will get all of their essential vitamins from a complete and balanced diet. Your dog needs fat-soluble vitamins A, D, E, and K as well as the water-soluble vitamins C and B-complex.

Fat-soluble vitamins are absorbed through the intestines and stored for later use. Because these vitamins are stored for long periods, there is a greater risk of toxicity when taken in excess. These vitamins are acquired through your dog’s complete and balanced diet.

  • Vitamin A helps with eyesight
  • Calcium absorption cannot function without vitamin D
  • Vitamin E aids the immune system
  • Blood clotting cannot happen without vitamin K

Water-soluble vitamins dissolve in water and are continually taken out of the body. Unlike fat-soluble vitamins, water-soluble vitamins are taken to the body’s tissues but are not kept for long. Your dog produces its own vitamin C and usually does not need any supplementation.

  • Vitamin C is an antioxidant
  • Vitamin B-complex includes thiamin, riboflavin, niacin, biotin, folic acid, vitamin B12, and vitamin B6. Assists with energy levels, brain function, and cell metabolism

How to Choose the Right Multivitamin Supplement for Dogs

Make sure to follow your vet’s guidance when it comes to choosing a multivitamin. Depending on your dog’s health, your vet will recommend which form of a multivitamin is most suitable for them. They will also direct you on which vitamins your dog specifically needs.

Best Dog Multivitamin Mix

Depending on what your vet recommends, you may want either a full mixture of essential vitamins or just one that is lacking in your dog’s body.

Make sure to follow your vet’s advice and pick the correct vitamins for your dog. If your dog needs a wide array of vitamins, double-check the multivitamin packaging for the list of vitamins.

Best Dog Multivitamin Supplement Type

Dogs might be famous for trying to eat anything they can find, but not all dogs take kindly to their multivitamins. Depending on your dog’s pill preferences, you might consider giving their vitamins as a chew, tablet, or liquid.

Perhaps the most unpopular option is the dreaded tablet. While some dogs have no qualms with taking a tablet, many others refuse to take them no matter how you disguise the tablet. However, with that being said, tablets are a guaranteed way of delivering the full dose to your dog – a chew can be partially eaten, and a liquid topping may be ignored. Vitamin chews are an effective way to deliver multivitamins to your pooch without them suspecting a thing. However, be sure that the chews are not too hard for your dog, especially if they have dental problems. As long as the supplement tastes good, most dogs will chow down on their liquid supplemented food with no problem!

Additional Ingredients

Are your dog’s vitamin supplements free from harmful ingredients and fillers? Make sure that your dog is getting all of their vitamins rather than a product full of unnecessary additives. Your product should be clearly labeled with no vague descriptions of what is inside. Two of the most common non-food fillers include talc and silicon. Food-based fillers include lactose and cornstarch. Artificial colorings are sometimes done for marketing purposes – these only function for people, not dogs! Finally, some gums that are used as emulsifiers cause allergic reactions.

What Are High-Calorie Supplements For Dogs?

High-calorie supplements for dogs are dietary additives that help underweight dogs to gain weight. They can also be used to prevent dogs with certain conditions from losing weight.

They contain super-dense ingredients that are naturally high in calories to increase or maintain the weight of the dog at a steady, safe rate. High-cal supplements should also contain key nutrients that support the entire body to help it accommodate the influx in calories.

The majority of high-calorie supplements come in the form of tasty liquids, gels, pastes, and powders that can be either eaten off the end of a finger or mixed in with food, which is especially useful for fussy eaters.

There are also generic supplements that are suitable for different pets, which are ideal for animal shelters, and dog-specific supplements, which are great for owners. Some dog-specific supplements are suitable for all dogs, while others are designed for either puppies or adults.

When looking for a supplement for your dog to stimulate their appetite, consider their needs, too. For example, high-fat content supplements are best suited to dogs who need to gain a lot of weight. Others double up as muscle builders for large and active dogs, and some focus primarily on weight gain/maintenance during illness or illness recovery. There are even appetite builders for anxious dogs and those with added nutrients for joint support for senior dogs.

You will have to tailor your dog’s dosage according to their size via the instructions that come with the product. If your dog is severely underweight, your vet may advise that you build up their dosage gradually, as to not overwhelm their body.

Key Features

Key ingredients to look out for include:

  • Healthy fats from natural sources (e.g. fish oil and coconut)
  • Protein from natural & high quality sources
  • Key vitamins and minerals
  • Omega 3 & 6 fatty acids
  • Probiotics & other digestion aids such as flaxseed and pumpkin

Things to avoid include:

  • Allergens
  • Chemicals & synthetics
  • Fillers
  • Artificial additives & preservatives
  • By-products
  • Added sugar
  • Trans fats

Other things to you may also want to consider:

  • Vet-recommended or trusted brands
  • Products approved by official bodies
  • High ratings & good reviews
  • Ethically & sustainably sourced ingredients

Pros of using weight gain supplements

Although you should still (and always) feed your dog a sufficient, nourishing, diet, the biggest pro of using a weight gain supplement is that it gives you peace of mind. You know that your dog is getting the number of calories they need to gain weight in one convenient product.

Cons of using weight gain supplements

If you do give your dog a weight gain supplement, you must make sure you give them the recommended dosage every day and stick to it until they’re healthy. Otherwise, you could wreak havoc with their body.

Another con is that weight gain supplements, like all supplements, can also have side effects, so make sure you read about the possible side effects of the product online or in the pamphlet that comes with the product.

Dogs & Weight

Like all animals, dogs can become overweight or underweight. Their ideal weight range depends on their breed, size, and age. Your vet will tell you your dog’s ideal weight and monitor it at annual check-ups, but the American Kennel Club also has a weight chart that you can use.

Weight Loss

Dogs can lose weight from illness and stress. Metabolic disorders such as diabetes, cancer, diseases involving the major organs, such as liver disease, parasites, gastrointestinal conditions, dental diseases, maldigestion disorders, and malabsorptive disorders can all cause dramatic weight loss and prevent weight gain.

When there is no apparent cause for weight loss, owners should look for other unusual physical symptoms such as changes in the coat and ask their vet for an examination.

Stress can also cause dogs to lose their appetite and therefore lose weight. Other symptoms of stress include panting, pacing, and destructive behavior. Common causes of stress include separation anxiety, boredom, being underexercised, phobias, trauma, life changes, and illness or death in the family.

Underweight Dogs

A good way to tell if a dog is severely underweight is if their ribs and lumbar vertebrae are easily felt and visible, and their waist and pelvic bones are prominent.

One of the most common reasons dogs become underweight is malnourishment from starvation. Malnourishment often occurs in rescue dogs and is usually a result of abuse or neglect, but it can also be due to homelessness.

Preventing Weight Loss & Gaining Weight

When a dog is underweight, vets often prescribe a special diet of high-calorie, high-protein, high-fat, nutrient-rich food to help them gain weight. This food should be given on a regular feeding schedule, which may include slightly smaller but more frequent meals than usual. Light dog exercise is usually suggested to increase appetite, and for those that need a little extra help, vets may recommend using a weight gain supplement as well.

If a dog is at risk of becoming underweight, vets may suggest a special diet, using a supplement, or both, depending on the situation.

If your dog’s weight loss has an underlying cause such as illness or stress, you should address the underlying issue first. Once your vet has diagnosed your dog, you can start to treat or manage their condition and focus on gaining back the weight. If your dog is experiencing stress and you cannot eliminate the cause, try to do some positive association training or invest in some anti-anxiety products. A fixed routine, lots of interaction, affection, exercise, play, and mental stimulation will also help too.

Best Dog Multivitamins: FAQ

Have questions about dog multivitamins? We gathered all the frequently asked questions by pet owners and provided the best answer for their queries.

When should you give your dog vitamins?

Your dog might need multivitamins to combat a nutritional deficiency. Nutritional deficiencies can be caused by imbalanced homemade meals, poor quality pet food, parasitic infections, and health conditions like diabetes and chronic kidney disease. Although vitamin deficiencies are uncommon in healthy dogs, it is best to talk with your vet about your dog’s health if you are at all concerned.

Through physical examination and blood tests, your vet will be able to tell you exactly what your canine pawt-ner needs. Depending on the cause of your dog’s deficiency, they may need one or more specific vitamins, meaning that one product may be more suitable for your pooch than another.

What kind of vitamins should I give my dog?

Depending on your dog’s needs, your vet may recommend a specific type of vitamin supplement. If your dog takes tablets well, you may find that a regular multivitamin tablet is best for your pooch. However, picky or senior dogs may benefit from chewable tablets or liquid multivitamins.

You must also consider your dog’s intolerances and allergies when choosing which vitamins to give to your dog. To make supplements tastier, many manufacturers will use real chicken or beef flavoring. If your dog is allergic to chicken, a chicken-flavored multivitamin could be dangerous for your pooch.

How do I know if my dog has a vitamin deficiency?

In general, a nutritional deficiency causes skin and coat disorders, a lack of energy, and a change in toilet habits. Specific vitamin deficiencies will affect dogs in different ways. For example, vitamin A deficiency may cause dull skin and coat as well as night blindness. Your dog’s muscles may deteriorate, leading to general weakness. Similarly, vitamin D deficiency can cause muscle weakness. Your dog may also be at a greater risk of heart failure, osteomalacia, and cancer. Vitamin E deficiencies are rare but are known to cause muscle weakness and decreased fertility.

Only your vet can diagnose a vitamin deficiency. Even if you feel that your dog’s symptoms match a vitamin deficiency, you must seek veterinary advice for your pooch. This is because other diseases can mimic vitamin deficiency. Also, vitamin deficiencies themselves can be caused by underlying digestive problems, so it is important to rule this possibility out before supplementing your dog with multivitamins.

What vitamins are bad for dogs?

Multivitamins for humans are not safe for dogs. Not only are our doses different, but many multivitamins for humans contain harmful ingredients. One of the most dangerous vitamins for dogs is prenatal vitamins. These vitamins are often high in iron and may cause iron toxicity in dogs.

Vitamin D supplements may also be dangerous when eaten in excess. Too much vitamin D can increase your dog’s risk of renal failure and heart problems. Gummy multivitamins pose a different risk to our furry friends. Many gummy vitamins are made with xylitol. Xylitol is extremely toxic to your dog, even in small amounts. When eaten, xylitol causes hypoglycemia, liver failure, and seizures in dogs.

Do puppies need multivitamins?

Until your puppy is weaning, they only need their mother’s milk and do not need additional multivitamins. This is because mother’s milk provides all the nutrition your pups need.

Once your puppy is weaning, their transition to a solid diet begins. This solid diet should be balanced and complete. If so, your puppy will not require any additional vitamins from you. Giving your puppy extra vitamins can be extremely detrimental to their health. For example, giving too much vitamin D can cause radius curvus syndrome in puppies.

The best multivitamin for dogs varies from dog to dog. While one dog will love chicken-flavored multivitamins, others will only need a liquid vitamin to supplement a deficiency. Be sure to check with your vet before giving your dog multivitamins.
