Small dogs are considered senior citizens of the canine community when they reach 11-12 years of age. Their medium-sized friends become seniors at 10 years of age. Their larger-sized colleagues are seniors at 8 years of age. And, finally, their giant-breed counterparts are seniors at 7 years old.
Your aging dog may have difficulty adjusting to the arrival of a new puppy. He could find a young whippersnapper's high energy and playful attacks irritating and react aggressively. Watch for signs of dementia in your dog. He may start to forget commands or other trained behavior he grasped when younger.
Just like senior citizens need more sleep, an older dog sleeps a lot when compared to their younger counterparts. On the higher end of the scale, a senior dog can sleep up to 18-20 hours a day, says Dr. Rossman. She estimates that the lower end is probably around 14-15 hours per day.
Most dogs enter their senior years at around 7 years old, a little sooner for larger dog breeds. They begin to slow down, they may gain weight more easily, their senses start to dull. An older dog's behavior will give you plenty of hints as to what he needs, but sometimes it helps to put it in words.
The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years (the max is 20 years), medium and large size dogs typically 10 to 20 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.
Stage 5: Adolescence (6 – 18 months) This can be the most difficult time during a puppy's development – adolescence. Your cute little puppy is becoming a teenager and will start producing hormones which may result in changes in behaviour.
The most prominent sign that you will notice is a complete relaxation of the body, your dog will no longer appear tense, rather they will “let go.” You will notice a slimming of the body as the air is expelled from their lungs for the last time and you may notice the lack of life in their eyes if they are still open.
Changes in your dog's behavior may be a normal part of aging or a symptom of a disease like dog dementia (canine cognitive dysfunction). Therefore, you need to consult your veterinarian should he exhibit signs of confusion, disorientation, memory loss, irritability, unusual pacing or other personality changes.
The average lifespan for medium-sized dog breeds is 10 to 13 years, with some breeds living even longer. As with small dogs, exact age ranges for medium-sized dog breeds are hard to determine, but there are general lifespan guidelines for each breed.
In general, small dogs enjoy longer lives than do their larger counterparts. A recent analysis of veterinary records revealed that dogs under 20 pounds had an average lifespan of 11 years while those over 90 pounds typically lived for only 8 years. Medium and large dogs fell in the middle at around 11 years.
Australian Cattle Dogs
Bluey, an Australian cattle dog, entered the Guinness Book of World Records by living to the ripe old age of 29 years and 5 months, setting the record for oldest dog ever.
Animal memory is thought to be much more simplistic than human memory, and dogs have episodic memories, which means they are only able to remember certain events in their life. While your dog will remember you leaving the house, they most likely won't understand how long you were away.
When there are too many bad days in a row, or if the dog seems to be turned off to life, quality of life is compromised. Bad days may mean nausea, vomiting, diarrhea, seizures, frustration, unrelenting pain/discomfort, or inability to breathe.
Some dogs will become restless, wandering the house and seeming unable to settle or get comfortable. Others will be abnormally still and may even be unresponsive. Your dog's sleeping patterns may change. He may become cranky and difficult to handle, either due to pain or disorientation.
Their body will go completely limp. If still open, their eyes will have a blank stare. Their heart completely stops beating. As all tension leaves their muscles, they may release urine or defecate as the muscles that control these bodily functions completely relax.
Small dogs are considered senior citizens of the canine community when they reach 11-12 years of age. Their medium-sized friends become seniors at 10 years of age. Their larger-sized colleagues are seniors at 8 years of age. And, finally, their giant-breed counterparts are seniors at 7 years old.
Changes in behavior can signal an underlying physical problem or may be a normal sign of aging. For example, if your sweet dog has suddenly turned grumpy, they may be in pain caused by arthritis or be experiencing some other physical discomfort. Or your high-energy companion may be sleeping hours a day.
Since dogs who are approaching death are often aware and ready, they may begin to act differently in their last moments.
