In 2004, a study reviewed 5 other studies of feral dogs published between 1975 and 1995 and concluded that their pack structure is very loose and rarely involves any cooperative behavior, either in raising young or in obtaining food.[82] Feral dogs are primarily scavengers, with studies showing that unlike their wild cousins, they are poor ungulate hunters, having little effect on wildlife populations where they are sympatric.[83]:267 However, several garbage dumps located within the feral dog's home range are important for their survival.[84] Even well-fed domestic dogs are prone to scavenge; gastro-intestinal veterinary visits increase during warmer weather as dogs are prone to eat decaying material.[85] Some dogs consume feces, which may contain nutrition.[86][87] On occasion well-fed dogs have been known to scavenge their owners' corpses.[88] Puppy potty Training

Taking the learning from Stages 1 and 2, we now test the dog within a public environment with real life distractions. This period can be the most challenging for the dog. Using a range of public locations we train the dog to utilise learned behaviours.During Stage 3 we expect the dog to work on verbal commands only, asking for a higher level of obedience. The training is still fun. At this stage, we have usually exchanged the food reward for a toy.
Yes, a training collar is completely safe for your dog. This is because they only use sound, vibration, or citronella spray. Each of these is completely harmless and designed to give your dog a surprise as opposed to an electric shock. They are effective for training, and they will not cause increased aggression because your dog is not feeling any pain, they are just a little startled by the sudden sound, sensation, or smell. 
Emotional contagion is linked to facial mimicry in humans and primates. Facial mimicry is an automatic response that occurs in less than 1 second in which one person involuntary mimics another person's facial expressions, forming empathy. It has also been found in dogs at play, and play sessions lasted longer when there were facial mimicry signals from one dog to another.[12] Puppy potty Training
The following tricks are based on search techniques used in professional dog training organizations. The information is simply to give you a taster and help you to entertain yourself and your dog you will have a lot of fun and enjoy the results of this training. The same command word is fine to be used for all of the search tricks, seek or find are good examples of search commands.
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

Domestic dogs appear to pay little attention to relative size, despite the large weight differences between the largest and smallest individuals; for example, size was not a predictor of the outcome of encounters between dogs meeting while being exercised by their owners nor was size correlated with neutered male dogs.[36] Therefore, many dogs do not appear to pay much attention to the actual fighting ability of their opponent, presumably allowing differences in motivation (how much the dog values the resource) and perceived motivation (what the behavior of the other dog signifies about the likelihood that it will escalate) to play a much greater role.[34] dog training classes

3)      Find their Passion. What does your dog prize most?  Food? If so, what kind of food?  A toy—what toy?  A bone… well, you get the picture. Some dogs (like the above mentioned puppy-mill rescue) will do back flips for praise said in just the right tone.  Discover what your dog loves and give it to him after each successful potty run. For the first month, withhold that “thing” until after pottying.  Play or let him chew on it for 10 minutes, then set it aside for the next potty period.
Resource guarding is exhibited by many canines, and is one of the most commonly reported behaviour issues to canine professionals.[50] It is seen when a dog uses specific behaviour patterns so that they can control access to an item, and the patterns are flexible when people are around.[51] If a canine places value on some resource (i.e. food, toys, etc.) they may attempt to guard it from other animals as well as people, which leads to behavioural problems if not treated. The guarding can show in many different ways from rapid ingestion of food to using the body to shield items. It manifests as aggressive behaviour including, but not limited to, growling, barking, or snapping. Some dogs will also resource guard their owners and can become aggressive if the behaviour is allowed to continue. Owners must learn to interpret their dog's body language in order to try to judge the dog's reaction, as visual signals are used (i.e. changes in body posture, facial expression, etc.) to communicate feeling and response.[50] These behaviours are commonly seen in shelter animals, most likely due to insecurities caused by a poor environment. Resource guarding is a concern since it can lead to aggression, but research has found that aggression over guarding can be contained by teaching the dog to drop the item they are guarding.[51] go here for more
