I was actually surprised by how affordable they are around here. I think it's $25 for a single session and $40 for a double, or somewhere in that range, and twice a week. So, ~$50 a week for a month to have a healthy dog again? OKAY! My dogs have not needed it yet, but when I dogsat a couple summers ago two of the dogs needed it twice a week for arthritis, and it REALLY helped them.
