Fecal Accidents After TPLO Surgery, Antibiotics and Weight Loss

Reader Question
Mt dog had TPLO surgery 8 weeks ago. In addition to the muscle loss she developed a MRSP injection and was on chloramphenicol for 5 weeks. After 3 weeks she quit eating. After trying everything we could think of to get her to eat we called the vet and asked if we could discontinue the last couple days of meds. We made her boiled ground meat and boiled chicken with vegetables and got her eating again, but she had already lost about 15-20 pounds. She is now going to the bathroom in the house. We take her outside and walk her for 15-20 minutes and as soon as she comes in she runs around the house dropping fecal matter in several rooms. It is normal consistancy. We just do not understand what is happening. In addition, her tail is not normal. It is constantly hanging straight down or is between her legs.

The vet is concerned with nerve issues and wants to giver her another week to get the meds out of her system. It has been one week since she has been off them. I cannot find information anywhere telling me that chloramphenicol has this form of side effect. When she got home Aron surgery she had a shaved spilt on her spine near her hind end. Could they have done a spinal tap and damaged something?

We are at a loss on what
to do. We don't want to give her up but cannot live with a dog that cannot control her bowel movements. We are at a loss on what to do.


Answer from Our Team

We're sorry she's been through so much. A hanging, limp tail together with poor bowel control does suggest a problem with the nerves at the base of the spine or tail. Chloramphenicol can cause hind-limb weakness or nerve problems in some dogs, and loss of appetite is a common side effect. These often improve after the medicine is stopped, so tell your vet about the timing, and ask whether she needs a blood count. A shaved patch on her lower back is often from an epidural, a common pain-relief injection given for knee surgery. Nerve problems after an epidural are rare, and other causes are possible.

Muscle loss, weakness and a long illness can also affect bowel control. Ask your vet to examine her nerves and reflexes and refer her to a veterinary neurologist if it doesn't improve. Ask your surgeon too, since they will know exactly what was done. Meanwhile, feed her at set times and take her out soon after each meal, and keep her in an easy-to-clean area. Make sure the surgical site has healed, and call your vet promptly if she gets worse or seems in pain.
