There are several reasons a dog may not have learned to play. One common reason is a lack of early socialization. Some dogs don't play simply because no one has ever engaged in a game with them. Another reason is that their instincts may drive them to do other things.
In dogs that are playing, the vocalizations are steady and varied. If you notice the intensity of growling increasing, including the “roar” kind of growl and body stiffness, this is a dog that's no longer playing.
A subtle sign your dog will give to let you know they are aware they're playing with a toy is ignoring it. When dogs play with their squeaky toy, they often may quickly drop the toy and ignore it to go do something else, which they will rarely ever do with a live animal.
Playing Dead as a Defense Mechanism Entering into a motionless, catatonic state often dissuades predators as their instinct to kill drives their feeding behavior. Since most predators avoid dead or rotting animals, displaying thanatosis in addition to producing foul odors is enough to keep predators at bay.
Behaviors that say it's all good fun Exaggerated, bouncy movement. The dogs are acting silly. Loud, continuous growling and snarling; again, exaggerated. Play-growling may sound scarier than serious fighting.
The key is to make sure both dogs are engaging at similar levels and do not look stressed. If both dogs are play bowing, bouncy, or seem to exaggerate their movements and vocalizations, it's likely a play session. Another good indication of play is sneezing.
Many dogs will bark when playing with dogs or people to show how excited they are. These playful growls are signs of happiness. These barks are sometimes accompanied by a “play bow” when dogs bow their front legs and wag their tails.
Chronic Bronchitis and Coughing Canine chronic bronchitis produces a dry, hacking cough in dogs that worsens with exercise and excitement. It is caused by persistent inflammation of the airways. Inflammation swells the lining of the airways and produces mucus which further narrows the passages in the lungs.
Coughing when excited is due to the dog breathing harder or more rapidly. This could be a sign of an allergy or mild respiratory tract infection, something irritating the lining of the throat. Watch for the following: Fever, Vomiting, Listlessness, Lack of appetite, Halitosis, Nasal discharge, Watery eyes.
Enjoyment of Playtime and Walks Happy dogs enjoy playtime and walks, and most even love rides in cars. While all dogs slow down with age, if your dog seems abnormally quiet, uninterested in favorite activities, or is less social, this may be a sign they're not feeling well.
If your pet is depressed they may be hiding more. "You may find them sleeping under the bed or in a closet. This is a common sign seen with depressed dogs," says Ochoa. If they are disappearing or trying to be withdrawn in odd places in the home, they could be feeling stressed or sad.
As the end of your dog's pregnancy approaches, you'll notice a significant enlargement of her breasts and nipples, and might even detect some milky fluid as the milk glands develop and enlarge. Her abdomen will increase in size and may sway a little as she walks.
