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. 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. 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.
Do not scold your dog harshly if you catch him urinating in the wrong place. Calmly say, "No," and bring him to his potty place with a piece of soiled paper towel. Only scold your dog for going in the wrong place if you catch her in the act. Do not drag her back to a puddle to scold her. She will not understand that it is the location of the urine that is the problem and may even begin to fear urinating in front of you.
Once upon a time, shock collars were just that. If they came with any intensity settings at all they were something like “High,” “Super High,” and “Lobotomy.” But that hasn’t been the case for a while and even the shock collars that “shock” are now so low it won’t actually hurt your dog; more surprise them. The “shock” is the same intensity of the shock you would get from a Tens electrode pad massage unit. If you’ve used them at all, you know it doesn’t hurt one bit. In fact, it can feel quite good in the proper context (but that context is not a dog’s training collar so don’t worry about him liking and wanting more of the jolt.)
Dogs differ from wolves and most other large canid species as they generally do not regurgitate food for their young, nor the young of other dogs in the same territory. However, this difference was not observed in all domestic dogs. Regurgitating of food by the females for the young, as well as care for the young by the males, has been observed in domestic dogs, dingos and in feral or semi-feral dogs. In one study of a group of free-ranging dogs, for the first 2 weeks immediately after parturition the lactating females were observed to be more aggressive to protect the pups. The male parents were in contact with the litters as ‘guard’ dogs for the first 6–8 weeks of the litters’ life. In absence of the mothers, they were observed to prevent the approach of strangers by vocalizations or even by physical attacks. Moreover, one male fed the litter by regurgitation showing the existence of paternal care in some free-roaming dogs. more on this
Your pup's actions tell you a lot about his mood. And although you may not be fluent in the canine tongue–short of what it means when it salivates–you do need to learn how to interpret dog behavior. Have you ever witnessed your dog licking certain textures or circling the same spot in front of you? There are many reasons a specific dog state of mind or health concern may cause him to do these things. Once you pay attention to his behavior, you'll be able to help him.
