No one likes to have to take their furchild to the vet, but if I must I appreciate the ways Commonwealth Animal Hospital tries to make things as painless as possible for pet and owner. Every time I have called for an appointment they have been able to fit us in on the next business day. They open at 7:30 and close at 6:00 so there is plenty of time for drop off and pickup without having to take time off from work. I also love that they have Saturday hours in case I have something that can't be easily explained and want to be there for the appointment.
They will always tell me if my kitty's normal vet will not be able to examine him (there are several doctors on staff) although everyone I have ever seen interact with him has been great. I am always asked thoroughly about what is wrong or (on follow up visits) how the treatment went. The treatments prescribed have always been effective even when I brought him in with vague complaints like "He seems more aggressive than normal".
Nowhere near the top of my reasons for liking CAH but still nice is the increased parking that was just added right outside. Parking in Midwood is not always the most fun, so I'll take convenience when I can get it.
