I agree with the above. Treats are great unless they are overly used. I'm a bad one for treats... I was giving them way to often and one of mine became a biter. I quickly fixed the problem but...
Now, I'm not a pro by any means but I have a tennessee walker and I have to say, I will try very hard to always have one in my barn. They are kind and obedient, they are safe and trustworthy, and they seem so regal and proud. My walker has a strange personality, he doesnt need me, but he's kind and lets me love on him and gives me all of his respect and trust. I'm not sure if it's just his personality or a walker thing, but he's not... Lovey dovey like some of my horses, he's kind and gentle but not lovey dovey... sometimes I think it depends on the horse. I will also say that it took me about 6 months to win him over completely as far as trust go's. Once I got it though, it's forever I think. Good luck with your TWH!!!!
