I was wondering if a senior dog could be fed Evo. Mark's friend's dog, Symba, always comes down for Hannah's dinner time so I have gotten in the habit of giving Symba a 1/2 cup of kibble mixed with the Evo canned. She seems fine with it but I didn't know if for some reason the regular Evo shouldn't be fed to senior dogs (she's 13 years old and extremely overweight). She's only used to eating Gravy Train and Alpo since they got her . They told me that's the only dog food she eats but she eat's the Evo like there's no tomorrow . I think they just don't want to shell out the extra money for the better food, no matter if you feed less and it'll be healthier for their dog or not. Anyways, is it ok to feed her the Evo, or should I get a senior formula for her when she comes down for dinnertime (mark will be really mad that I buy a bag specially for her but oh well).
