Sorry to hear this! When I saw the post, I went back and re-read my thread about Dakky and the crystals. And, I am glad to see that KAK posted her information. THEN, I clicked on your link and saw it was my post.

Daks still continues to do well on this, we have had a suspected URI or two in the 2 years since the surgery. According to the vet, that is cause his private parts are more open now, like a girl's. Dunno. He still licks, licks, licks a lot down there. I think it might be cause he dribbles a bit, and is stinky.

I never made the switch from Hill's C/D. BUT, I intend to after reading that KAK's boy is still having sucess on it.

Water intake is key. I still mix Dak's wet food with water. Like a mush, and he drinks it up.

good luck!
