I have and will again if the situation warrants. I had a youngster (now 9.5 + yrs young) who had a neck injury when she was ~16 mos old by my estimation. Suddenly she could not carry her 3rd or 4th duck from JH tests nor would she run down hill. Her neck was so screwed up! I tried my regular vet first (who is quite good w/ ortho, etc issues) and tried the rimadyl/crate rest etc. Did not improve w/ 3 mos. I asked her about alternatives since she suggested MRI was next. She gave me a reference, and he did a full exam and chiro on her, and suddenly I had my girl back! Ears down, eyes alert/happy, etc. Til she rolled over for a belly rub and everything came spilling out of alignment again. Her neck tendon was ALL messed up- subluxated by then because we had dinked around w/ crate rest and rimadyl. After a few attempts of chiropractic, the next step was prolotherapy and it WORKED WONDERS. She went on to finish her JH, CDX and do agility. I'd never have thought she could jump again but she's been fantastic ever since. It was maybe ~$1500 total at the time. Well worth it! I've since taken dogs in to him if I suspected they'd gotten out of alignment or whatever. Find a good one, and you've got a fantastic tool in your box. I used to have a site bookmarked, but I think if you google "find a holistic vet" they'll come up w/ a list of vets and all the modalities they are certified in. I have 2 other vets who I will use, depending on the situation. I think you have to in this day and age if you have more than a dog or 2 and possibly breed.
