Whether it's in your First Aid kit or somewhere else, it'd be a good idea to have booties for your pups. At least a couple booties.

In case they injure a paw and to prevent injury to paws.

Can't say my pup is enthusiastic about booties but she's worn them.

Also, a muzzle. If your dog is in pain, you don't want to also deal with them biting you as you try to treat it.

A friend's dog recently broke her leg and chomped on my friend's husband when he went to pick her up.
