Pete could have been a burro. He had extra long ears, four legs, and a vertebrae reinforced cow like tail with a fly swatting hair tuft at the end. Dad got him for us kids because he couldn't afford a horse. We found out later that dad didn't like horses because they are dumber then a dog. My mother hated any animal, but she hated horses the most. Each time any animal (except a goldfish or guppy) was mentioned my mother told her story of the planet's friendliest horse that only ever bit one person, my mother.
My dad liked animals; he had a pack of coon hounds (blue tick, redbone, walker and black/tan) costing an average price of over a thousand dollars per dog. This was back in the late fifties when a new car cost two thousand dollars. Pete the burro cost $400.
Some people called Pete a small jack-ass, they were thinking a jack-ass could be a mule, not so; mules are half horse and half burro. The horse is always the mother and a jack (male) ass on a ramp is the father. The Jack is actually called a "Mule-Jack." He is used only to create Mules; if he ever gets loose with a female donkey he won't mount a horse again. He is then called a "Jack-Off."
Switching parents is a bad idea. A big draft stallion father could split a female donkey in half at delivery. If the offspring survives it's called a Hinny. Pete was small, around 400 hundred pounds. Dad probably bought him for a dollar a pound on the hoof.
Ass is the common term that Pete could have been called. Dad bought a small saddle at an auction sale and girth hitched up Pete as a saddle ass. Pete didn't like the saddle. He liked it less when dad bopped him on the head with a claw hammer and slip rope choked him every time he bucked. Pete was a smart ass. He learned fast.
Pete never would cross a road. He must have had a bad experience with a man made surface in his former life as a burro. What this meant to the rider was that if Pete was in a full run and you arrived at a road he would stop by digging in his hoofs. You were still moving. Over Pete and on to the road you would skid. "Hee haw, hee haw." He always said that. On a hot summer day this was painful, as you slowly picked yourself out of the bloody bubbling tar puddle landing zone. Pete didn't like any type of artificial surface, grass was his friend. He loved grass.
Pete was a sexually active male. He liked females. Anytime either of my two sisters was around Pete, he was a big show off. His ears would reach for the sky. His nostrils would flare and start dripping male slime offerings. My sister's were young and could actually walk under Pete's belly. If they did, Pete would vibrate all over and a cloud of flies would seek a new home. Pete was in love.
