There have been more than 1 instance of Petsmart letting people walk off with other peoples pets - that was the most recent...Since I live in Houston this is becoming a problem and I do think Petsmart is going to be taking more security measures.    
But - I also have seen Many posts by people who were not happy with the Groomers in Petsmart - I would ask your VET if they can refer you - and also check with anyone you may know that also has a yorkie - I found myself grooming my 2 girls myself because I have yet to find a groomer I really love after going to FIVE in all -    
When your puppy is young though it's good to get him/her used to being groomed so I hope you have a good experience        |
