Acupuncture for dogs is considered extremely safe with no known side effects. The procedure is painless due to the use of very thin needles, and many dogs even find it relaxing. Unlike some treatments, acupuncture doesn't involve the use of drugs or chemicals, which eliminates the risk of adverse reactions. It's also highly compatible with other veterinary treatments, including radiation and chemotherapy. Given its safety profile and lack of side effects, acupuncture can be a beneficial option for dogs suffering from various health issues, promoting natural healing and pain relief.
