Puppy is just five months, recently had him fitted for a harness as he could slip his collar.
Yesterday he slipped the whole harness, I was left by a busy main road holding just the harness and lead while puppy played I bet you can't catch me in and out of parked cars. He throughly enjoyed it but I aged overnight.
I'm used to pointy dogs as already have a Deer hound Greyhound cross and I think his rough long coat stopped any slippage problems but tiny dog seems to be part seal his coat is so slippery, very slight, super flexible and inclined to panic and jump backwards at loud noises and boisterous other dogs.
We went out today with him trussed up with both collar and harness but I think he could probably slip both so need a quick solution.
Hopefully someone experienced in slippery dogs can advise.
