That's not a wolf. I've spent the last several years investigating wolf killings, so I've probably seen more than my share (both dead and alive).
The coat is way too thick, not coarse enough, and the head/skull is less angular than a timberwolf's.
I am not a pet expert, but I can't imagine that keeping an animal like a wolf as a pet would be very practical. Wolves like to roam and will travel upwards of 150 miles in a week. Mainly going where the food is, but that need to move is still imprinted in their DNA. I'd think a 'real' wolf would be miserable as a pet. They also need raw meat in their diet, which could get pricey (up to 5 pounds a day).
Then again, if they don't know any better and are born to it, I guess they could become accustomed to it. Dogs were domesticated over time. Who knows?
Here are a few wolf pics I've taken.
I spotted the tracks last winter. I wear a size 12 boot, so that's probably a good-sized wolf judging by his paw prints.
The penned wolves are on a game farm. They don't look all that happy. Kinda mangy and ragged, too.
The wolf rug is in my office, seized from someone by my predecessor.
No pics in the wild - I'm not that quick with a camera. I did see 4 a week or so ago on a rural road up here. Can often hear them howling at night, too.
