dog behaviorist in the houston, tx area

[Rowan]

Dose anyone know of a good behaviorist in the Houston area?

A little back story on my problem. (Well more of a long story..) A short time after I got Rowan at around 7 weeks I started taking him in my front yard and on very short walks around my house. Some of the kids that live on the street started to throw rocks at us, so he started to bark at all kids that comes around. He has gotten to where he will let a few select kids come up to him but 90% of kids he will bark at and if they try to come up with him he will try to run away from him. Like I said we were making good progress and we did go through puppy class where my trainer helped us out with his issues. Her next class will not start until the end of June. Now he has started to do the same thing to adults and I honestly don't know why. I am always taking him out with me, he goes up to my work most of the time once a week and I also take him with me anywere I go that will let me have a dog with him. This week I had all my confidents shattered by somthing I don't want to talk about. Also this week I took him to get his ears posted and he had an allergic reaction to the glue. He has blisters all in his ears and it took three people (me counted) to get the glue out of his ears and treat them today. I'm afraid that will set him back further. I can't wait around for my trainer to come back so dose anyone know a good behaviorist that could help us out?

I also do NOT plan on re-homeing him, I know we can get over this with the proper help.

Thank you in advance.
