It's very normal for Bulldogs to sleep about 17 hours a day. If it shakes and doesn't walk straight, take the dog to see a vet.
Hi. I breed English Bulldogs in WI. I have been sucessful in breeding healthy, quality beautiful bullies. Wostalenglishbulldogs.weebly.com. I would be concerned if my 11 week old weighed that little if it is pure English Bulldog. I have 12 week old pups and they are 18-24 lbs. The pup should be full of wrinkles, active for a bit then sleeping. At 11 weeks the pup should be good on his feet and running around. Visit a vet!
