I would say at his age this is extremely normal… some puppies will get excited and pee a little. If for some reason it becomes excessive I would mention it to the vet, potty training w/bulldogs can take some time… my bullies finally were fully trained between 6 to 8 mos and had some accidents after that. Best rule of thumb is to take them out regularly, I think that I started out w/every two hours and immediately after eating or playing. Good luck!!!
