Query: but as it is its not a good fit and i cant use it to walk him ...

it helps him to be calm during travel but i am still having trouble getting it adjusted .........i had originally purchased a medium and it was too big.....i sent it back and got a small.....i still cant get the adjustment right.....i cant get it to go smaller in the chest because the adjustment buckle stops at the harness and i cant go any further in the chest.....i gave it a 3 for fabric quality and a comfort source......but as it is its not a good fit and i cant use it to walk him as he slips out of it at the neck.
