Maria took great care of my 3 month old puppy!!

This was our first time with Maria, and not a positive experience. Maria already had a dog at her house who was kind of hostile to our black lab mix puppy (rescue), whose been socialized with dogs but is a little timid. The other dog was clearly stressed out and not into Caesar. Since the other owners were late and hadn't shown up, I just didn't feel comfortable leaving Caesar there. What sealed this decision was when the other dog kind of snapped/growled at Caesar and pulled back in fright thumped against a car. Maria had tried to take the dog for walk and leave Caesar alone, but this just didn't sit well with me since it was his first time meeting her & he's 17 weeks old and we haven't been leaving him alone for long periods of time. My suggestion is for her to not schedule dogs back back...give a larger window of time between pick up and drop offs.
