About Doreen:

I grew up in Sheridan Homelands until I married in 1990. My business experience consists of transportation, law enforcement, and banking.

In 1992, I bought a house in Streetsville. In 1995, I purchased my first dog, then more came. I’ve always had a love and passion for animals. You’ve probably seen me walking or driving in the area I live or service.

In December 2004, Wag-a-tail was born. In addition to my regular dog walking, consider Wag-a-tail for your family vacations, with my live-in services and home security checks while you are away. Have other pets needing care? No problem, I’m here to help.

With 19 years of experience and an excellent local reputation, you can rely on me to deliver the quality care you expect for your beloved pet.

My clients love my reliability, punctuality, and flexibility.

I’ve gone over leaps and bounds through the worst snow, ice and rain storms, and the hottest days. When clients thought I wouldn’t show up due to poor weather conditions. 

Wag-a-tail is there. Whether you are away on vacation or at work for the day, I have a reliable vehicle that gets me where I need to go.

Check out our featured review!

Wag-a-tail Pet Sitting has been our “go to” pet sitter for more than 5 years. Doreen has not only provided pet sitting for our 3 cats, but has kept an eye on happenings around the house and alerted us to problems. On one occasion, her quick response saved us from a potentially damaging flood within the house. In a previous snowstorm, Doreen walked from the main road into our street to attend to our cats, because even a four wheel drive couldn’t negotiate the snow banks. Having Doreen as a pet sitter gives us peace of mind when we are away from home for long periods of time.
