My dog's back leg is giving out, no swelling. Is it a snake bite?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Female | 7 years and 4 months old | 30 lbs

My Boston Terrier was out last night, and I knew there was a snake in that corner somewhere, and I have black snakes all the time. And I've noticed today that his right back leg is giving out on him. There is no swelling anywhere on him . Otherwise he and he wants to be in every room that I am in. And you can tell it hurts him. He was just at the hospital for fluid behind his ears last week he had MRI and stuff done, I paid a lot of money and really can't afford to take him back to the hospital.

If it was a poisonous snake, then it would cause a great deal of swelling, so I wouldn't worry too much about a dangerous snake bite. There are some nonvenomous snakes there that can bite and cause pain, but they are usually not that bad. I would suspect that something else could be causing the pain. It could be an injury to a muscle, tendon or ligament. It may be OK to wait a couple of days to see if it gets better. If Rocky is otherwise acting normal and you don't see swelling, then it likely won't hurt to wait it out. It really depends on the injury though and it's difficult to know without seeing Rocky. In the meantime, you can ice the sore leg for 15 minutes twice a day. This may help.
