Hi Laura,
when you see your vet does he take a sterile urine sample? Sterile urine sample give better results ….
Have you tried Royal Canine S/O Urinary dry, feed for breakfast & R/C S/O Urinary wet can for dinner, try for 6weeks, no other foods just feed the Royal Canine Dry & Wet.

Or look at Hills C/D MultiCare Wet food
Here’s the C/d Multicare Chicken & Vegetable Stew

The ingredients look pretty good, Phosphorous 0.54, you could feed the Hills C/d Multicare Chicken & Vegetable stew instead of the Science Diet dry formula & see how he goes…

Take your dog on 2 daily walks, dogs love sniffing & they love weeing on everything, get him into a routine morning walk & afternoon walk..
He will start looking forward to go on his walks, when Patch isn’t feeling well we go for a drive to one of the nice parks up the rd, I see a big smile on Patches face, tail waging as soon as he see’s the park.

You have to Email the pet food companies for the proper phosphorus %…
