Hi! I have a six month old English Mastiff named Bess. I got her when she was twelve weeks old. I am concerned about her weight although she is healthy it seems that she should weigh more. I brought her to the vets just the other day and she weighs sixty five pounds. She isn't a huge eater and I am not sure what route I should take as far as adding canned food to her dry food or what not. Any suggestions would be greatly appreciated.
