Ari is 8 month old Corgi who has started to lose weight & has became underweight despite eating 3-4 meals a day. She currently eats Blue buffalo dry puppy food. She did have an episode of vomiting about a week ago but we attributed to her getting into my dads dog's food while visiting. She still plays & acts like her normal loving self.

I agree with you. She is very underweight. This is very abnormal. I strongly recommend you get her to a vet for an exam. Hopefully this problem is due to something easy like worms but I am very worried it is more serious like an underlying congenital problem with her liver and/or kidneys. Please, get her to a vet. This is not a simple instance of her just needing to eat more or eat supplements. Hope this helps. If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.

I recommend to have Samson examined by the veterinarian. Not feeding enough calories per day can be a cause as well as intestinal parasites, organ disease, endocrine disorders among other causes can all cause weight loss. The vet may recommend running a fecal test to check for parasites and may also recommend blood work to check for signs of a problem. I hope this helps and please feel free to post any additional questions.

Even on a low-fat diet, excessive weight loss is not expected or normal. I recommend to have Dove checked for other potential problems such as kidney disease, cancer or progression of her liver condition. If no medical causes found, the doctor may need to change her diet or provide some sort of high calorie supplement to control her weight loss. You will first need to rule out other medical conditions. Best of luck.
