Complaint Review: Monrovia Animal Medical and Just Paws Pets

We bought a French Bull Dog from Just Paws in Aracadia and were told to take the dog to Monrovia Animal Medical Center for a check up. We were told there was no charge and if anything was found wrong with the dog Just Paws would pay the costs.
The entire situation has been on lie after another. To make a long story short this is how it goes...

Buy pet from Just Paws-They tell you dog/cat has received all vaccines from Dr. Gueniat of Monrovia Animal Medical Center. They guarantee the pet is healthy.

You go to Monrovia Animal Medical Center and your pet is examined by Dr. Guenait who proceeds to tell you test need to be done at your expense not Just Paws.

By the time you leave there they have stuck it to you for tests you didn't need and find yourself returning to Just Paws for an explanation.

I was told the following:

Dr. Gueniat of Monrovia Animal Medical Center gives puppies/kittens shots at Just Paws. She does not charge them anything for giving the shots. Just Paws will not allow you to take a pet purchased from them to any other veterinarian. You go to Monrovia and suddenly you are being charged for everything.
There is something really wrong when a pet store will not honor their health guarantee for a dog/cat purchased by them if you won't go to a veterinarian they have an arrangement with.
The arrangement is...they get free vaccines and the customer gets ripped off when they walk into the Just Paws veterinarian.
This is very suspicious and I would never recommend buying a pet from a store who won't allow you to have the pet checked out at the veterinarian of your choice.
If this isn't a bait and switch...I don't know what is!
