We spent a lot of time and effort making sure our matching algorithm is as accurate as possible. We take the information you enter on Petfinder (age, breed, gender, size, good with children, good with dogs, good with cats) and use it to calculate our matches. For example, a Husky is going to shed more than a Cockapoo. A Himalayan cat is going to have longer hair than a Siamese. A 13 year old English Bulldog is going to tend to have less energy than a 2 year old Cattle Dog. Mixed breeds add another layer of complexity into the calculation. Is it an exact science that will be correct 100% of the time? Of course not! Every dog or cat is an individual and may stray from the norm. However, it gives your potential adopters an excellent starting point when looking for a new pet.
