my dog was suffering from difficulty in peeing,i went to the vet he did an xray and ultrasound nothing came out,then he did a urinalysis and found out too much cystine crystals in his urine.The vet told me our only approach now is to change his diet (u:/d from hills) and stop giving him chicken (which i give him everyday mixed with dry food).He also gave me antibiotic for 8 days. After i went home i found out that this is a very rare condition and diet is not enough.What should i do?

Cystine stones are quite rare and if large require surgical removal - you report however no large stones were identified on ultrasound so it is possible it was the small crystals and inflammation which were causing the signs. Therapeutic diets are used to prevent the formation of stones and are vital in dogs with cystine crystals or those recovering from stone removal. A repeat urinalysis and specialist ultrasound (possibly following catheterisation under sedation to ensure nothing is lodged in the pelvic region which is very difficult to scan) would be required if symptoms persist or worsen as even one small stone can cause a potential obstruction
