Scruffy was found in September as a stray at a gas station in Houston, Texas during hurricane Harvey, the Hamilton, Ontario Spectator reports.
The terrier mutt was suffering from a severe ear infection that has left him deaf.
Marina Bourguignon, who is fostering Scruffy until a permanent loving home can be found for him, is teaching him commands in sign language.
"He's a beautiful dog," she says. "He's so loving. I don't understand why he isn't adopted yet. There's nothing wrong with him except that he's deaf and he just learned sign language. He knows come, he knows sit, he knows lay down, he knows quiet. He learns fast."
Believed to be about 2 years old, Scruffy is one of 39 dogs who were retrieved after Hurricane Harvey by dog rescue agency Redemption Paws. They were delivered to the Ontario Society for the Prevention of Cruelty to Animals (OSPCA) headquarters on Sept. 11.
In total, Redemption Paws has rescued more than 80 dogs affected by Hurricane Harvey.
