A Little Vicious (1991)

Bandit, a Connecticut house dog with ties to the Pit Bull family, is condemned to death for biting an aggressive neighbor and then his own remorseful master. But when the late great dog-trainer and philosopher Vicki Hearne steps in, a judge grants him a 90-day stay of execution--and a chance to prove that old dogs can learn new tricks.

Unfortunately the movie A Little Vicious is not yet available on HBO Max.
