After all this time trying to find out why my POA is so sore and miserable & thinking it is founder. We have had many vet opinions & most have leaned to founder with an old hip injury. Anyway a new vet came out to do xrays but after looking at her we decided to run blood work first & do xrays if that didn't show anything. She has been so bad we were talking about putting her down so she didn't suffer anymore. She barely can take a step, shivers, all over body aches. All four legs are lame - shifts from one to the other. Has needed bute 2 times a day ( barely helped) The tests they ran showed positive for lymes disease. I started her on Doxycyclin - 37 capsules a day. ( a real pain to open each one & to give her) She won't eat it in her food & now are trying to mix up in a syringe. This has to be given for 28 days & may or may not help. I hope we didn't catch it too late. She is only 8 years old & has more personality than 20 horses put together. We have had to rig up a temporary heated stall since it was -22 this morning & too hard for her to stay warm even with the blanket & leg wraps on. It isn't a real warm stall but much warmer then having the wind on her along with those bitter temps. Anybody ever have a horse with lymes? Any other great ideas to help her would be appreciated. The vet also thinks she does have a broken pelvis ( old injury) & maybe a slight case of founder last year but her feet didn't show any pain when he tested them.
