Dogs have an olfactory sense 40 times more sensitive than a human's and they commence their lives operating almost exclusively on smell and touch.:247 The special scents that dogs use for communication are called pheromones. Different hormones are secreted when a dog is angry, fearful or confident, and some chemical signatures identify the sex and age of the dog, and if a female is in the estrus cycle, pregnant or recently given birth. Many of the pheromone chemicals can be found dissolved in a dog's urine, and sniffing where another dog has urinated gives the dog a great deal of information about that dog.:250 Male dogs prefer to mark vertical surfaces and having the scent higher allows the air to carry it farther. The height of the marking tells other dogs about the size of the dog, as among canines size is an important factor in dominance.:251 Puppy Training
Hands up is a fantastic trick that looks great. The dog is taught to sit back and hold both front paws up simultaneously. Easy to reinforce by offering the word hands up and a treat each time the dog manages to get both front paws off the ground. The pure position of this trick makes it look like it was really difficult to teach but if you reward with good timing early on then the dog will perfect his position with little effort from you. more
The term personality has been applied to human research, whereas the term temperament has been mostly used for animal research. However, both terms have been used interchangeably in the literature, or purely to distinguish humans from animals and avoid anthropomorphism. Personality can be defined as “a set of behaviors that are consistent over context and time”. Studies of dogs' personalities have tried to identify the presence of broad personality traits that are stable and consistent over time. more on this
