Space used by feral dogs is not dissimilar from most other canids in that they use defined traditional areas (home ranges) that tend to be defended against intruders, and have core areas where most of their activities are undertaken. Urban domestic dogs have a home range of 2-61 hectares in contrast to a feral dogs home range of 58 square kilometers. Wolf home ranges vary from 78 square kilometers where prey is deer to 2.5 square kilometers at higher latitudes where prey is moose and caribou. Wolves will defend their territory based on prey abundance and pack density, but feral dogs will defend their home ranges all year. Where wolf ranges and feral dog ranges overlap, the feral dogs will site their core areas closer to human settlement.[38] dog training collar

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.
A study using dogs that were trained to remain motionless while unsedated and unrestrained in an MRI scanner exhibited caudate activation to a hand signal associated with reward.[2] Further work found that the magnitude of the canine caudate response is similar to that of humans, while the between-subject variability in dogs may be less than humans.[92] In a further study, 5 scents were presented (self, familiar human, strange human, familiar dog, strange dog). While the olfactory bulb/peduncle was activated to a similar degree by all the scents, the caudate was activated maximally to the familiar human. Importantly, the scent of the familiar human was not the handler, meaning that the caudate response differentiated the scent in the absence of the person being present. The caudate activation suggested that not only did the dogs discriminate that scent from the others, they had a positive association with it. Although these signals came from two different people, the humans lived in the same household as the dog and therefore represented the dog's primary social circle. And while dogs should be highly tuned to the smell of items that are not comparable, it seems that the “reward response” is reserved for their humans.[93]
Yes – with a warning. Most bark collars respond to a bark with a negative stimulus: citronella spray, ultrasonic sound, or a brief shock. The problem, and the warning, is for homes with multiple dogs or even dogs nearby. For this reason, many bark collars come with adjustable levels of sensitivity, making it harder to set off or easier, depending on your specific situation. You don’t want your dog getting negative reinforcement when another dog is misbehaving; of course because it’s cruel but also because it will confuse him and make the collar worthless. So use these collars carefully and never when he’s in the company of other untrained dogs. dog training classes
