Hi, My presa canario puppy just turned 4 months yesterday and I've been noticing that she's having some trouble putting on weight. She just weighed in at 34 lbs. Her sister and littermate, on the other hand, seems to be doing much better. I'm beginning to feel very concerned as I have already switched her food once and it seems to have given her bouts of diarrhea and upset stomach. Now that she's somewhat used to the food (Blue Buffalo PUPPY Wilderness, no grain formula), I'm wondering whether I should switch to something that isn't quite as rich? My question to other presa owners is what food is mostly recommended in this case, in order to help with weight gain as well as to improve her stool (it varies from solid to liquid). The vet has had a look at her and says she's not unwell and simply needs to switch to something her stomach can handle better. Any help would be appreciated! Thanks.
**Also, I've attached a most recent pic of her, incase someone would like to see how she looks in terms of weight, etc.**
