Due to circumstances beyond my control my ole mare needs to wear a heart bar shoe.  After putting them on the next day she was so much more comfortable and the soundest she had been all summer.  With that said....

HOW do you keep the dang things on?  Is anyone else here experienced with them and have any tricks of the trade to keep them on? 

Try and bell boot

Yup the rubber bell boots.

Joy Wargo has a video out there on how to tape the foot to help protect the shoe under the bell boot.

Is she pulling them off by pawing or just moving around and stepping on the back of the shoes with her back hooves? I have a gelding that is bad about pulling off his front shoes, he likes to run and spin while turned out and pulls one everytime, so I decided to try the cheap rubble bells with velcro, (the pull ons I cant get on so gave up on the pull ons) so went with the velcro ones and got them a little bigger so they would hang lower on his heel bulbs and they have worked like magic, no more pulled shoes.. These are the ones I got, I bought about 3 pairs thinking the cheapos would fall apart real fast but they are holding up real good, still on the first pair and this has been almost a year of using them.

I do not know why these pictures got dark as soon as I post they look normal and then they turn dark for some reason. But these are the 7 and 8 dollar boots..

I have had a set of bells on since she pulled the first one off.  The bell was on and we lost the second.  The bell i am using is not that rubber kind but i think i can come up with a set of those to try. 

for those using bells, do you have the back feet squared off?

gonna go check out the tape job also. 

Yes, I have my farrier square up the back hooves..I get my bell boots a little big so they will go over the heel better and touch the ground, if your bells dont touch the ground your horse can still pull the shoe off, the bells need to beable to cover all of the back of the hoof and even/touching the ground.
