I took my 32 month old male Alapaha Blueblood bulldog to the vet because his urine was dark and he had not been eating, plus his stool had become creamy. They did blood and urine test and gave me antibiotics for him. They said red and white cell count were low I noticed his jaw was locked closed and side of jaw swollen when I attempted to give him the pills. He yelped now I am not sure what to do, He did get into a little rough housing with a dog over the weekend at the dog park. Help

I think tetanus causes lock jaw.

Go back to your vet
