Practice everywhere, with everyone If you learn that two plus two equals four in a classroom, you’ll take that information with you wherever you go. Dogs, however, learn very specifically and don’t automatically apply their knowledge in different situations and places as well as people do. If you teach your dog to sit on cue in your kitchen, you’ll have a beautifully kitchen-trained dog. But she might not understand what you mean when you ask her to sit in other locations. If you want your dog to perform new skills everywhere, you’ll need to practice them in multiple places-your home, your yard, out on walks, at friends’ houses, at the park and anywhere else you take your dog.
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. how to potty train a puppy
Dogs (and wolves) mark their territories with urine and their stools.[37] The anal gland of canines give a particular signature to fecal deposits and identifies the marker as well as the place where the dung is left. Dogs are very particular about these landmarks, and engage in what is to humans a meaningless and complex ritual before defecating. Most dogs start with a careful bout of sniffing of a location, perhaps to erect an exact line or boundary between their territory and another dog's territory. This behavior may also involve a small degree of elevation, such as a rock or fallen branch, to aid scent dispersal. Scratching the ground after defecating is a visual sign pointing to the scent marking. The freshness of the scent gives visitors some idea of the current status of a piece of territory and if it is used frequently. Regions under dispute, or used by different animals at different times, may lead to marking battles with every scent marked-over by a new competitor.[6]:252–4 more on this
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. 
The range on this collar is nearly 800 yards. It’s an appropriate choice for training any dog from 15-120 pounds and puppy to fully-grown dog. The collar is adjustable in length and the unit’s mini-size allows you to use on your dog for extended periods of time without it bothering him. That in itself will go a long way towards training but the ease of use with the remote control will be sure to tip the scales in favor of this collar.

When dogs are separated from humans, usually the owner, they often display behaviors which can be broken into the following four categories: exploratory behaviour, object play, destructive behaviour, and vocalization, and they are related to the canine's level of arousal.[47] These behaviours may manifest as destructiveness, fecal or urinary elimination, hypersalivation or vocalization among other things. Dogs from single-owner homes are approximately 2.5 times more likely to have separation anxiety compared to dogs from multiple-owner homes. Furthermore, sexually intact dogs are only one third as likely to have separation anxiety as neutered dogs. The sex of dogs and whether there is another pet in the home do not have an effect on separation anxiety.[48] It has been estimated that at least 14% of dogs examined at typical veterinary practices in the United States have shown signs of separation anxiety. Dogs that have been diagnosed with profound separation anxiety can be left alone for no more than minutes before they begin to panic and exhibit the behaviors associated with separation anxiety. Separation problems have been found to be linked to the dog's dependency on its owner, not because of disobedience.[47] In the absence of treatment, affected dogs are often relinquished to a humane society or shelter, abandoned, or euthanized.[49]
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
