Question: where did you get this animal?
This is an important question to ask someone who is advertising a pet on a buy/sell forum such as Kijiji or Facebook. It is important to understand if you are communicating with a rescue, a breeder, a person whose pet had an accidental litter, a puppy mill-type organization or even perhaps a scammer.
Anyone selling a pet in Nova Scotia is required by law to provide a Veterinary Certificate of Health, but when a pet is given away, there are no such assurances.
In a personal re-homing situation, be aware of the commitment you are taking on, because you may not have the ongoing support or option to return the pet should it not be the right match for you.
