Hi I was hoping someone could suggest something for my little girl. She will be 2 on December 18th and she has digestive issues it seems. She is really skinny and everytime she starts to put weight on she starts having really loose stools and the weight just falls off. She is currently eating Taste of the Wild - Salmon and Potato as that seems to sit best for her, she only wants to eat about 4 cups a day though. She got really sick last winter and I ended up having to cook for her every day for 4 months - she dropped 30lbs in 2 weeks, got the weight back on her and she seemed fine again. Other than not being able to have processed chicken or grains the vets say she's healthy and they can't find anything wrong I'm worried it is starting again as she has dropped 10 lbs in 2 weeks. She remains active, always ready to play and isn't lethargic. But she has terribly loose and frequent stools and occasional vomiting. Has anybody else had these issues with their English Mastiff?
