DOG TRAINER QUERY:
Can anyone recommend any good dog trainers and/or behavior therapists in the Houston area that specialize in big dogs for a German Shepard / Mastiff mix? He was rescued off the streets about a year ago and he’s a bit unpredictable with his aggression. Basic training has not helped with him – apparently it's fear aggression due to whoever his previous owner was. Name/phone/email/website/contact info would be helpful.
**Note: This is not for my dog....my George is PERFECT!! :) I am asking for someone else who wanted a referral. I have never met this dog, so please don't ask me any questions; all I know about him is what I posted. Thank you to anyone that can help.
