Wolves as dogs lift their hind leg while urinating

With dogs this behaviour is only common with most male dogs, while only a few female dogs perform this behaviour. 

With wolves it’s quite a different situation as both the breeding male and the breeding female both urinate with one of their hind legs up. The subordinate wolves in the pack - both males and females - do not pefrom this behaviour, but rather sit down like it’s common for female dogs to do.

Wolves display an extremely strict, complex social hierarchy within their packs - much of which is expressed through relatively advanced communication through body language. This strict social ranking is effective in promoting social unity and order, which, in turn, greatly increases their success and survival, and contrary to some perceptions, prevents conflict and aggression. In an established pack, rarely do problems escalate to a physical level.

From ZooBorns.com:

6-Week Old Arctic Fox Brothers:

"During the winter months, white phase Arctic fox have white coats that serve as camouflage against the vast stretches of snow and ice in their native Arctic region. When the seasons change, their coats change to a brown or blue-gray appearance that allows them to blend in with the summer’s landscape. Blue phase fox, more common in the species’ southern habitat range, remain charcoal-colored year round. Young of each color phase may occur in the same litter."

Vulpes lagopus - arctic fox.
The one with blue coloration which is caused by recessive genes. It’s probably trainsitioning cause its fur is too dark for winter coat and not enough dark for summer coat. Blue arctic foxes’ fur never get snow-white.

Raccoon Dog (Carnivora: Canidae: Nyctereutes procyonoides)

Often mistaken for a badger or a raccoon, the raccoon dog is actually more closely related to wild dogs. That being said, they act more like raccoons as they scavenge for berries along riverbanks. Raccoon dogs are often hunted as pests. Their luck in the illegal fur trade is no better, often attracting the attention of animal welfare groups. Their adaptability in the wild allows them to quickly become an unwelcome invasive species out of Asia. However, this sneaky trickster is well honoured in Japanese folklore as a master of disguise. Raccoon dog, or “Tanuki”, figurines are often places outside of Buddhist to bring good fortune by showing off a friendly smile.

So here’s a thing: All these dogs pictured above are purebred German shepherds.

The top two are from American show lines. They are bred solely for appearances and are not required to have any working titles. They are not required to pass any temperament tests and are not even required to be free of hip displaysia. These are (generally) some fucked-up German shepherds. 

The next two down are from German show lines. German breeding regulations require all breeding stock to have schutzhund or herding titles, but this is not the top priority for show breeders, who continue to produce dogs with absurd conformation. 

The bottom two are from European working lines. They are bred for drive, health, and temperament. The goal is to produce a dog who will not just prove to be sufficient to obtain titles in herding or schutzhund, but who will excel in a variety of working endeavors. These dogs embody what German shepherds are meant to be: Healthy, hearty working dogs.
