A little "update". Wonder if any of you have any views or suggestions?
The diagnosis is struvite crystals, and we will be doing the special food they recommend to break the crystals down.
Unfortunately, my dog is already on a special diet for very bad skin problems. That diet (vet recommended) sorted out her skin, but I now wonder if it played a part in forming these crystals?
Hey, ho, all fun and games..............I'm sure we'll find a diet that suits eventually, but we are going round in circles right now!
