Hi. (1st time here...) 4 yr old was on california natural and just started w/soft stool. Vet recommended i/d in the can- when I introduced dry it didnt help. Then went thru a series of dry foods, now 6 mths and still not working. Last week we started iams proactive and added boiled chiken & rice. For 3 days now it has been like a finger over the hose- but now he doesnt even seem to want to eat the chk & rice. I am really scared that we are doing serious damage to him. Vet checked stool and urine says all is fine. Should I make him fast for one day and then slowly re-introduce food? We are giving him a probiotic and antibiotic too. It has me so worried now I cant even sleep.
