Time varies as well. Depending on what your dog needs, but around one hour to 2 hours per dog
If your dog has bitten before, please let me know. I will try to groom the dog as is, but if I feel any sort of attack is coming, I will use a muzzle on the dog to protect him/her and myself. I use open muzzles, meaning they can still breath and be comfortable they just cant harm me or themselves.
