Hi there, I posted a week ago in the behaviour section as my 10 mth old Lurcher cross was scavenging a lot on walks and in the garden and consequently has the runs, 80% of the time. I was given many opinions, including changing his diet and maybe a muzzle but didn't want to try too many things at once as i still didn't know the cause of the loose poos! I got a muzzle which he has been wearing on walks and when he goes in the garden. He hasn't been able to scavenge for a week now but still has very loose poo. Should i change his diet?? I'm a first time dog owner and i'm not sure what is best. We used to feed him Wainwrights dry puppy food, but he had the rund with that, so we changed him to Purina BETA dry food at 7 mths and put him on the adult food. Any advice..........??
