re: Dog Help Advice Needed- Growling and Baring Teeth

Hey man... it could very well be challenging you. But I had a 2.5 year old bullmastiff was an excellent dog started to do the same with me. Come to find out she had cancer of the jaw bone and a tumor inside of her ear. It devastated me. Just get your dog checked out. It may be nothing but bad habits but it wouldn’t hurt to get the dog checked out just in case it has some underlying issues.
