I read one of your other threads discussing your vet's thoughts about food allergies (rice in particular) and a wish to remain on the Z/D to determine the allergy possibility.
If I hadn't read that first - I'd be suggesting to you that (a) you should ditch the Z/D; (b) you should ditch kibble in entirety; and (c) that a raw diet that included no grains whatsoever would be a far better idea - but if not possible or acceptable to you, then a homecooked diet that likewise excluded grains (and, initially, vegetables or fruit) would be the next best thing.
However - you are in the position where your vet is trying something else. I guess you have to make the decision about how long you stick with it before deciding that it is or isn't working. IF you get to the point that you are sure that you're getting nowhere with the Z/D - then what I suggested above is the advice I'd give then
Colitis is quite a common problem with boxers - and it's often ulcerative colitis with this breed. Those dogs just don't tolerate processed foods, dehydrated foods, or grains. Kibble is strongly all three, and most colitis sufferers will never tolerate that sort of diet. A few may improve on a grainless kibble diet, but the majority simply cannot tolerate kibble - period. And for many of those dogs, a raw natural diet actually
is the magic bullet. LOL - there are very few health situations for which magic bullets exist, including raw diets. But with colitis - many times that's the case.
Anyway - whether or not you want to consider raw is really up to you (and you might choose to stick with your vet's regime a while longer too). But if you reach a point where you want to consider it - the raw forum is there to help
And if you prefer to go homecooked - I really would stress that if it's colitis, grains are highly unlikely to be tolerated and vegetables are likewise risky. So it would make more sense to head in the homecooked-but-grainless direction should you look into homecooking to try to help her.
