MountainMutt Fights Canine Cancer
Our company was inspired by Mac who was diagnosed with bone cancer in September 2009.
It’s cold in the Rockies! Mac’s deep chest and short back made it hard to find a coat that fit. We made a black leather coat for Mac, lined with warm, toasty fleece. It became our prototype winter coat. Our designer dog coats are made for cold, snowy Rocky Mountain winters!
5% of sales is donated annually to the Flint Animal Cancer Center yearly for cancer research. Coats are donated to needy dogs and rescues around the USA.
