Sometimes dehydrated foods (add your own water) can be a cheaper alternative to canned, but they have just as much moisture once rehydrated. Worth checking out. I do not know if any are suitable for the treatment of struvite crystals.

Also, a dog water fountain that you plug in worked for my UTI-prone dog. The Big Dog Max is for larger dogs (I use the CatMate for my little ones).
