Any dog emergency center (affordable) around Houston?

Just came home from working a late shift and found my dog in the backyard bleeding and likely needing stitches (in the ear) I suspect neighbors dog was in my backyard . I’ll deal with the specifics later, right now I am going to clean him up and look for somewhere to take him.

Any affordable recommendations? I want the best care for my senior dog but I also am struggling with bills right now so I am willing to travel for something affordable
