One of the main reasons why dogs and puppies whine is because they want your attention. They usually do this when they want to interact with you and seek your affection. Dogs and puppies also whine due to hunger or pain.
Your dog may be peeing on your bed due to stress, as a response to fear or as a means of marking territory. Similarly, your dog peeing in awkward locations around the home may be due to an underlying medical condition or a side effect of using certain medication.
Just like in humans, female dogs bleed when they get their periods. This period is known as the heat or estrus cycle. The onset of the heat cycle in female dogs varies. Some female dogs may start their first period within their first year of life. The duration of the heat cycle also varies in dogs. Some canines have heat cycles extending up to four weeks.
Unlike human mommies, dogs do not stop going into heat, meaning that menopause is not part of their reproductive system. Most dogs enter their first heat cycle at the age of 6 months and reach sexual maturity thereafter. As dogs get older, the interval from the last mating phase of the estrous heat cycle to the next gets extended.
Dogs lick furniture commonly due to pica, among other reasons. Pica is a condition when dogs have a craving for inedible things and like to chew them up. You should treat this behavior with urgency by visiting a veterinarian.
Female dogs first go into heat at around six months of age. This can be sooner for smaller dogs and a little later for bigger pooches. Once female pooches reach puberty then they will go into heat approximately once every six months, but this can be irregular in their first few years of life.
The most common reason why dogs lick everything is out of compulsion or an obsessive-compulsive disorder (just like OCD with humans). They may also be expressing boredom or trying to show affection to their favorite people through licking.
As discussed below, there are many reasons why dogs bark at nothing including attention-seeking to get rewards like toys, frustration, greeting barking, illness, injury, etc. Some owners can quickly identify the reason why their dogs are barking by listening to the specific type of barking.
Your dog may cry, or bark, growl or whimper, in its sleep because it is dreaming. It is believed that dogs go through phases of electrical activity in their sleep, just like how humans do. Your pup is therefore capable of dreaming and even having nightmares.
