He walks with a cane. Shuma assists him. Is he a true service dog, I doubt it but he does aid him in his disability.
As you said, either way, the chick is plain mean.
A service dog is defined as any dog that is trained to perform at least one task that mitigates it's owner's disability. If the dog is trained to help himit is a true service dog and legally had to be allowed to accompany him in his apartment even if they had a no pets policy.
I live in a place that has a no pets policy and we have a service dog..and recently obtained two more. (I have three kids with disabilities).
