Why is my active puppy so thin and not gaining weight?

I wouldn't recommend adding any additional food to help Simba bulk up - you should just increase the amount of puppy food that he gets each day. You could try increasing by about 25% for two weeks and then judge his body condition using this scoring chart to see if he seems like he is an appropriate weight. If your veterinarian recommended a specific diet for his diarrhea that he is still eating you should check with your veterinarian first to make sure it is okay to increase the amount of food offered or if there is something else he should be fed. Since he is feeling better he should gain weight quickly - don't forget to cut back on food again once he seems like he is back to an ideal weight. http://www.mabcr.org/template/upload_files/PuppyBodyCondChart.pdf

Most puppies should be proper weight if they are getting fed puppy food, and in his case large breed puppy food. If you are concerned about his weight, then I would recommend getting him checked to ensure he isn't losing nutrition due to intestinal parasites, which is the #`1 cause for weight loss in puppies. Otherwise, he may just be naturally lean. I can see his ribs there but he is laying down, if he stands and his ribs are still readily pronounced, then he may be a tad bit underweight. Also if he has any loose stool, this can indicate other internal organ issues that should be checked by your vet. If he has an underlying issue that is not treated, then no matter what you feed him, he will continue to be undersized. I hope that things work out well for your pet Thunder and that his weight normalizes soon! Best wishes and take care.

Simba is underweight for his age and breed. This puppy cereal and curd are not a balanced diet for a puppy, and it will not give him the nutrients he needs to grow properly. In addition, the lack of nutrients will lead him to be weak. He needs to be on a puppy formulated dry food only. Brands I recommend include Royal Canin, Hill's Science Diet, Purina ProPlan, and Iams. Please go out and buy him some puppy food now. I would also take him into a vet right away. I'm quite concerned about his weight, the fact that he won't eat food, and that he's sleeping all the time. He needs veterinary care right away. Best of luck.

I would recommend a really good deworming since he is young. However it would be best to take a fecal to the vet to determine if he has parasites and if so what kind. If he does not have any parasites I would recommend a food change. I would try a basic diet like purina, royal canine, or science diet puppy food.

First you want to make sure that Teddy is parasite free as parasites will rob his body of nutrients. Secondly, some breeds are naturally thin at his age. When he goes in for his next veterinary visit, make sure to ask the doctor about his weight. Lastly, don’t be in a hurry to put weight on Teddy. Rapid changes in body condition are not good. Instead feed a high-quality, small breed puppy food. Brands like Royal Canin and Science Diet have additional calories in their small breed formula which is different than a normal puppy food. I hope this is helpful and please feel free to post any additional questions.

Thank you for submitting your question regarding Yukon. It can be difficult to keep weight on some young very active dogs. First, he should see his veterinarian for blood and urine testing to ensure there is no underlying disease that is affecting him. If he is deemed healthy, then you can consider another brand of food. Some dogs will respond better to one brand over another. I would stay within the performance line of foods though with the 30:20 ratio you are using. You can feed more than the bag recommends if necessary and supplement with canned food. Your goal is to be able to easily feel all of his ribs and see the last few for him to be at a healthy weight. He needs a defined waist from the top and side views as well. Lastly, neutering him will slow his metabolism and result in weight gain. I hope this information helps!

You should have Zena examined by your veterinarian to make sure she is healthy. At the same time you can get her wormed (worms could be a reason for not gaining weight), and vaccinated. You say her dam and sire did not look healthy....there could be a congenital problem that could keep her from gaining weight. Feed her a good quality complete puppy food for medium to large dogs and feed her according to the instructions on the bag.
