We took pup into a small, local (non-chain) pet shop today, to pick up a few bits. He was wearing his collar and lead. The lady in the shop asked if he had a harness, why he wasn't wearing one, didn't he like it etc. She said we should really use it to protect his throat instead of the collar.
As it happens he does have both, I just find the collar easier. He is a small breed and doesn't pull much (no more than you'd expect a 4 month old pup!) So I guess my real question is, am I being dreadful careless? Is the collar going to hurt him?
