Head bobbing while cantering
So I've had my tb mare since June last year. She's been getting fatter over the winter so this spring I started working her a lil more for show season. We went to our first show in April and she did great. Acted perfect, rode perfect. Couldn't be more happy. But as of recently, while we're cantering she wil bob her head up and down. I know they should do a slight bob while cantering but she is really bobbing. She just started to do this about a week or so ago. It's kinda annoying and hard to keep my hands still when she does that. Any ideas???
