Features to Consider for the Best Dog Weight Gainer

When dog owners are choosing the best dog weight gainer, the ingredients should be on the top of your list, because there are significant differences between what manufacturers use to make these products. Usually, higher-quality products have more costly ingredients, which is reflected in the price. For me, to choose the best dog weight gainer means to choose the highest quality that offers what I want.

Here are the main considerations when choosing the best dog weight gainer:

Ingredients

The considerations here are if the ingredients are natural or artificial. Is there any fat component of a healthy kind, and is it from a clean source? Are the protein contents bioavailable and not a potential cause of an allergic reaction? I do not like artificial stuff made up in a lab. Grain free dog food and organic dog food are usually the best choices, whether as a wet food or kibble dry food.

Taste

Taste is very important because even the best dog weight gainer is useless if your pet does not like the taste of it. The only way to find out if your pet likes a particular product is to buy some and try it. Your pet should relish the taste of it or at least not notice any difference and not have to be forced or reluctantly eat their food with the supplement mixed in.

Format

These best dog weight gainer products to help malnourished dogs come as tablets and powders. I like the powder style because it mixes in more easily with the food, and I can adjust the dosage to the exact weight of my dog.

Benefits of Using Dog Weight Gainers

I am mostly concerned with how the best dog weight gainer makes my dog look and perform. However, I can also see the benefits of using a weight gain supplement like these for older dogs or to help a dog recover from an illness or a surgery when their appetite is not strong. When I volunteer at the animal rescue, I notice they use these products to help emaciated rescued animals regain weight and muscle growth on the pathway back to good health after suffering from neglect and abuse.

After they are weaned from their mother, scrawny, sickly puppies benefit from having a nutritional supplement added to their food as well as nursing mothers who lose so much weight when feeding their pups. Any dog, of any age or condition, benefits from taking a dog weight gainer in their food if they need to increase their weight to have a stronger metabolism, gain muscle mass, and improve health.

Precautions of Using Dog Weight Gainers

It is a good idea to always consult with a veterinarian before using any of these products. Things to look out for when using these products are intestinal distress and allergic reactions to the ingredients. Even the best dog weight gainer may cause problems.

Many dogs will react to any changes in their diet by vomiting. This is normal for a very short time until their digestive system gets used to the food mixed with the supplement. If you have this problem, try giving only a very small amount and slowly increase it until your pet builds up a tolerance. This should only last a few days at most. If your dog continues to vomit up the food, change to a different product after letting the dog eat normally for a few days without any supplement in their food.

Allergic reactions may cause respiratory problems, stomach upset, skin rash, and/or diarrhea. At the first sign of an allergic reaction, stop giving the supplement immediately and take your pet to the veterinarian if the animal is distressed.

Any animal with a cancerous tumor should not be given any supplement that boosts weight gain without first consulting with a veterinarian. If you improve the nutrition of the animal that has cancer, you may increase the rate of cancer growth as an unwanted consequence.

I already spoke about the dangers of any product containing propylene glycol. I do not recommend it. I prefer using natural products rather than artificial ones. Be aware that even if a product says it is “Made in USA” on the bottle, the ingredients used to make it may be imported.

Conclusion

My choice for the best dog weight gainer is Buddy & Lola Healthy Weight Gainer Supplement for Dogs. My dog loves to eat pumpkin. Before I gave him this supplement, I was already feeding him cooked organic pumpkin in his food, for the nutrients that it has. I thought I was the only one who knew the benefits of feeding a dog pumpkin! Then, I discovered this product has pumpkin protein in the supplement mix.

The only artificial ingredient it contains is the flavoring, which makes it taste like bacon and maple. My dog likes the flavor, so this ingredient seems to be fine. I hope whatever choice you make for a dog weight gainer keeps you and your beloved pet happy and healthy for a very long time.
