Story

Hi, I'm Willy! I'm a curious fella with a heart of gold. I'm still growing into my long lanky legs and so I'm a little goofy sometimes. I prefer slow, appropriate approaches to new people and new situations because I'm a little nervous about them at first. I'd love if my new family could help to advocate for me that I don't want new people rushing up to me, even though I am super cute. Once I'm more comfortable though I'm a bundle of enthusiasm and would welcome a game of fetch or a romp in a fenced yard. If you would like to meet me, I'm staying at 115 Woodcrest Dr in Pembroke. Give us a call at 613-635-7508 or email at renfrewcounty@ontariospca.ca. My adoption fee is $585. It includes my neuter, vaccinations, dewormer,microchip and much more!

Hi, my name is Max, Male - neuteredMastiff St. Bernard MixApprox. 1 year, 6 months oldI'm a cheerful and lovable goofball, sometimes blissfully unaware of my size, but in the best possible way. I certainly know how to pose for a treat, though let's be honest-I'm always a sight to behold! I love going for walks and bringing along my favourite stuffed toy for the journey. If you want to play outside, just look at my tail wagging high with excitement! However, what I truly need is a quiet home without children or other animals. This kind of environment allows me to relax and thrive, ensuring I can be the best companion for you. Primary Color: White Secondary Color: Brindle Weight: 38.005 Age: 1yrs 7mths 2wks
