My puppy has weak legs, limps, and a pus-filled pimple. Vet needed?

Updated on September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | unneutered

I recently got a 11 week old puppy. He twitches alot in his sleep. Which seem to me like involuntary muscle movements in his legs and around his face. His back legs seem to be weak when eating and shakes. He also tends to walk a little limpy and sets crooked. He also has this wierd pimple on his leg that had puss coming out.

It sounds like Charlie has a bunch of problems at the moment. Twitching during sleep can be normal, as dogs dream and can move in response to those dreams. But the weak back legs, walking limpy, and sitting crooked isn't normal. He also could have puppy pyoderma causing the pimple. You need to take him into a vet first thing in the morning. Best of luck.
