Morgan had struvite stones removed last year. The vet was happy with him eating Burns, said it was one of the best and therefore he wouldn't try to sell me anything else (I presume he meant Hills food which he stocks

)
Since then I have changed his diet a bit in any case, and he now has Burns only for breakfast and raw in the evening to help increase his moisture levels (his pee has always been very strong

) His breeder suggested giving him cranberry tablets to help acidify his urine, this was in the early days of his problem when we thought he had a straightforward bladder infection,but I have since continued to give him one of these daily and I do a urine test regularly to check his PH levels. Morgan is not a great drinker and this aggravates the problem so every day I put about half inch of water in his bowl with a teaspoonful of salmon oil which he thinks is just yummy and he licks the bowl clean! I also put a little cold water on his Burns in the morning (he doesn't like warm water as it makes the kibble go too soggy

) He also only has filtered water in his water bowl but then again he always has, and yet he got stones so I don't know that doing this on its own is enough if you have a dog who is prone to bladder problems.
