Most terriers seem to think they are ten feet tall.
And they are rather aggressively affectionate -- they just know you want to pet them.
I don't have a problem with aggressive affection, Unless it involves taking a piece of my finger off.
Actually out walking my dogs, I have tried to cultivate every dog in the neighborhood.
There is a little terrier of some sort at the end of the block. I don't know if she is just a barker for the joy of it. She seems happy to see me, and lets me pat her but she still barks her lungs out.
She looks like she might weigh 10 lbs soaking wet.
