Went to pick my dog up and she said he had a tiny nick. When I got him home I realized it was actually over an inch long and a chunk of skin that was cut off, not a nick. This is fairly significant in size for a 10lb. dog! I had to take him to the vet, and I had keep it clean and bandaged, per the vets instructions. He took over 2 months to heal completely, and still has a scar. I do not recommend this groomer.
