Chester was taken to the Animal Friends Humane Society in Hamilton.
When he was shaved, a velcro toy was found underneath all his matted hair.
Once he was completely groomed, he found a forever home and is now featured in the Dirty Dogs Contest.
The online contest features 10 dogs and photos of what they looked like when they arrived at shelters across the country, and after they were cleaned up.
Public votes will determine the top three winners. The animal shelters or rescue groups affiliated with these transformations will receive grants to further support their efforts. First place takes home $5,000, second place receives $2,000 and third place earns $1,000.
The Dirty Dogs Contest runs until Aug. 1.
