I really hope I can get some reliable advice from posting here. I have a 6 year old mare who is kind of a "mutt" so to say. My vet says that she has some Morgan in her. She is a small horse, standing at 14-15 hh. She has a lot of energy and has a lot of troubles with just walking, instead of trotting. I purchased this horse from a summer camp that I work at and have had her almost 2 years. When we had her at camp we always rode her in a Tom Thumb bit - just basic. I have been since riding her in just a tom thumb. The problem that I have is that she likes to kind of "blow through" her bit. When we go on trail I always have to keep a very tight rein on her and even then I can't get her to just walk. By the end of the day, I am frustrated and she has to be sore as her neck is bent the entire time and her mouth has sores from her bit. I haven't cantered more than 2 times on my horse since I bought her and have never galloped on her. She flexes really nice on the ground and under the saddle but it seems that she can't walk and when she gets past a walk she isn't interested in what the bit has to offer. I basically have no control over her when we do canter and the one time I asked her to slow down (a slight pull back and quick release) she came to a dead stop and almost tossed me over the front of her. I don't get it - she doesn't listen to the bit and blows through it but then all of a sudden she stops on a dime and decides to listen. I guess at this point I am at a loss as to what to do. Should I switch my bit? The only reason that I hesitate is because she flexes so nicely (which is a new revelation - she hadn't really understood the concept of flexing until recently) and is so responsive when we aren't walking/trotting around. The only other thing I can think of is if her saddle is pinching her. I have tried multiple saddles and all have produced the same results. Some times when I get on bareback she walks around no problem but other times she is dancing around like she has places to be. So basically, I am open to ANY and ALL advice as long as it isn't rude and hurtful! Thank you in advance for anything you are able to offer - I truly appreciate it!!
