i thought they floated naturally? my choccy lab loves the water and is a great swimmer. Looks like a big otter when she gets in though!
I think they're like the other pet clothing, just over-priced **** that dopey women buy and then say 'awwww, isn't it cute.' No it's not. the thing looks bloody stupid.

Best one i heard is 'he looks just like a person'.

What, with the fur, four legs, shorntess and waggy tail?
Oh and i agree, you don't need a strap to lift a jack russel out. In fact best thing to do with a jack russel is leave it in there!
