I took this 135 lb. pure bred American Bulldog for a one mile walk last night around 10 PM.
It was the first time I've walked my area at night without carrying my sidearm, or 4' section of galvanized pipe for protection.

How does he like the taste of Chihuahuas?
Actually, he belongs to my daughter's boyfriend, and that picture is of another dog, but they look exactly the same. The pictures my daughter took last night before I walked him did not come out worth bass poop, so I took this one off the Internet.
We (I) are dog sitting until my daughter's boyfriend arrives back from Hawaii after attending his sister's wedding.
He is really well behaved and playful with most dogs out in social circles, but when he is chained up in the yard... you cannot approach him as a human stranger, or another strange dog, hence I must keep my gates closed 24/7.
He is still a pup and growing. He is known as the Bully version of an American Bulldog and is expected to get > 140 lbs., even bigger, after he gets fixed.

He is all muscle and can easily break standard rope with a tensile breaking factor of 120 lbs., hence is why he is tethered with plastic coated steel cable.
He gets along quite well with Bell, as long as he is tethered.
She knows he can only get out so far and teases him quite often, until I scold her, and tell her to knock it off.
Earlier, I unhooked him, and let him roam the property, but can't leave him unattended.
He can be quite destructive with stationary things, such as cars... tires... trees... what-ever-he-can-get-a-hold-of.... etc.

I let Bell out to do her thing and the little chihuahua immediately realized he was not tethered.
Never realized how quick this little dog can be ....

Getting ready to take him for another walk right now, as it is another well moon lit night, and this big boy needs to get rid of pent up energy.
