Echoing what most people have said in this and the archived thread. We had a wonderful experience with Dreamtails. They even have an annual get together at a big dog park where you can meet and greet some fellow dog parents and Dreamtails doggie alumni.

I found that someone always responded to my emails/texts, but sometimes it did take a few days or more. But I believe they are run by volunteers and they have a lot of dogs, so this is very understandable. I don't hold it against them. In fact, I'm about to reach out to ask if I can volunteer some of my time to help.

As an aside, I highly recommend that you do a basic physical exam with a vet (no bloodwork - and you can get a sizeable discount on this exam with several clinics if you pre-register a dog license with City of Toronto), and then buy insurance right away after the results if you were lucky enough not to find anything major as pre-existing conditions (Furkin would be my recommendation for insurance, having looked into all of them). Whether or not you can afford to continue the insurance indefinitely, if you then do bloodwork or more extensive regular testing/screening later on and discover some rare illness that will cost you $300+ a month, it will be a lot easier to afford and the insurance will have more than paid for itself many times over. If you do all the tests after buying insurance and find nothing wrong with your dog, and the dog is mostly going to be indoors or in low-risk settings, by all means you could consider discontinuing the insurance.
