Hi, I am a new member and I created my account in the hope that one of yall can help me. I have a 8 month old female doberman that I have had for about 4 months and she currently weighs 50 lbs. When my family first got her my parents took her to the vet and she had a puppy checkup and said she was fine. At first I feed her blue buffalo but she didn't seem to interested in it so I switched her over to Taste of the Wild and she still isn't eating as much as she should. She is a active dog, she has no problems running around for a our and a half with the other dogs at the dog park. Usually she eats between 4-5 cups a day depending on how much exercise she had, I give her as much food as she wants but she never wants to eat more than 5 cups. I give her food twice a day and I took her to the vet again one month ago and found out she had round worms and I gave her medication for it. Since the last visit to the vet she has only gained ~3 lbs. Any ideas on why she isn't putting on weight?
