I took my dog to the vet to get pills for her separation anxiety (breaking out of cage causing herself to cut her face up multiple times, runny poop anytime left alone for more than 5 hours, taking her to the dog park, being around people) she gets very sad when we leave and very excited when she's around other people or other dogs. She has always looked very thin, but she ONLY weighs 60 lbs. This is not normal for this breed. I am hoping that with this medication, it will help her gain weight, (Hoping she is just small from how much she poops, and how it upsets her tummy). I feed her Blue Buffalo large breed puppy chicken and brown rice. She always has food in her bowl, she probably only eats about 4 cups a day, but there is always food in the bowl she just wont eat a lot. Any advice on how to fatten her up?
