Honestly, due to a horrific incident, I'm pretty shaken up at the moment. My french bulldog killed a cat (street cat). I tried to stop her, yet she wont listen. I even kicked her -- to let go of the cat -- but she just kept on biting the cat until the poor thing died! I've never seen her this aggressive before :When my dog (Erykah) woke up the next day, she started limping. I'm really concerned about this incident. I'm taking to her to a vet today. French Bulldogs are really good with kids, however, I'm really worried now. I've always had this impression that she was a sissy dog. She's so friendly and adorable! She's really good with humans, plays with complete strangers.and rarely barks. By the way, this happened in my front-yard. What would you recommend to PREVENT this from happening again?
