Anyone know of a black-owned dog grooming/daycare/training businesses around Houston?

I have a nearly 4 year old dog. He’s a red heeler mix. And normally, he’s very sweet and afraid of everything. But I recently discovered he’s aggressive towards people of color.

I live in an apartment complex and have neighbors from all over the globe. You can imagine how mortified I am when my sweet boy turns into a monster around my black neighbors and delivery people. And I can only imagine the fear he invokes in them as the ones he’s directing it towards.

I am determined to get him exposed to people of all skin colors so that he’s safe for everyone to be around. But instead of asking my neighbors, and traumatizing them further, I’d prefer exposing him to people who understand dogs and have patience for them.

Are there any black-owned dog businesses or trainers around Houston that you could share with me?

I’m desperate for help here. I need him to be a safe dog for my community and stop his inappropriate behavior.

Thanks in advance!
