Excuse me for reinvigorating this thread...I came across this while researching sudden aggressiveness in bulldogs.
We've had our Tebow for 2 years - he is 3 years old (male, we believe purebread).
We've had some issues with aggressiveness but could pin it to certain actions (eg, don't pull him away from food).
Last night, though, he became problematic. Went after me on 2 different occasions with no or little provocation.
first time, I was kneeling in front of a kitchen cabinet and he came up next to me sniffing - not problem - but then started snarling and barking and my husband had to pull him away.
A second time, I had just point topical powder on his tail (bald due what is likely an allergy hot spot) and I bent down behind him to clean up the stray powder. My husband was giving him a treat and he became angry and chased me into the kitchen and grabbed by shorts with his teeth.
He had been to the vet on Monday and received several vaccines (2 shots) - no rabies, however.
The vet was a woman but he has always been more accepting of my husband as alpha as opposed to me.
I wanted to see if Devine's dog got over the issues.
And if anyone else has any insight, please send to me.
