I've had 3 dogs get acupunture and all did well, however I do not do chiro as I don't think it's a good idea to manipulate the dog's neck/back since they can not tell you how they are feeling. Things CAN get worse with chiro, but not acupunture. The worse that can happen is... nothing. With chiro- if the necks is having problems, too much manipulation can hurt.
That is IMHO, of course. There are several folks right here on GT that have hounds do well with chiro as well. Until the dog is feeling better, they should be on pain management and wean them off the pain meds once you are 5-6 weeks into the treatment. It usally takes several times for it to work and it can get worse before it gets better.
Freddygirl (Nancy) just had a dog diagnosed with bulging disks. She has posted about her issues too.
