Expensive, but worth it.
Bought for my working cocker to prevent any paw injuries (and expensive vet bills) whilst mountain hiking in Snowdonia. Also purchased the socks which make getting the boots on easier - especially on a dog with fluffy feet. The socks also protect the dew claw.
Getting him used to them was hilarious - imagine Bambi on ice! Didn't laugh at him though as advised - just plenty of praise and treats!
