So Sorry this is happening! Please do not give up! i agree with the other wise and wonderful posters about contacting a dog behaviourist if possible. i am not sure if that has something to do with your own size but it may be depending on how long this has been going on. Hopefully things will improve soon. Hugs. Sending many safe, warm hugs to BOTH you, @BigBubba, your Family, your Friends and ALL of your Loved Ones! Keep fighting and keep rocking NO MATTER WHAT HAPPENS, OK?!
