Hi, I have had a 5 year old shih-tzu for the last 4 months. He previously belonged to my friend but she fell pregnant so I took him. He had always been fed on complete wet dog food, butchers cartons to be precise, but I've been told that these will be no good for his teeth and to switch to dry. I've tried him on iams, and then ardens grange complete dry and he ate them for a day or two but then nothing. I've tried mixing it with wet, I've tried adding a bit of tuna and brine, which worked for a bit, but he won't touch it again. What are the health reasons for dry food? Is it just for his teeth? And if so could I not just give him dentistix along with wet food? Sorry for the essay, he was being looked after by a friend for a few months before I took him and he was fed on rubbish so I really want to try and get him eating some decent food now.
