The top five causes of sudden unexpected death among 151 dogs were, in order, heart disease, toxicosis, gastrointestinal disease, trauma, and hemorrhage not associated with trauma.
In a study of autopsies performed at Purdue University Small Animal Diagnostic Laboratory1 over a five-year period, nearly 10 percent (112 cases) had been associated with sudden unexpected death.
The last few days before your dog passes you may notice: extreme weight loss, a distant look in their eyes, a lack of interest in anything, restlessness or unusual stillness, a change in the way that your dog smells, and a changed temperament.
If your dog is experiencing lethargy, fatigue, and lack of interest, it may be depressed. You may notice that your dog is sleeping more than usual or isn't interested in activities, toys, or people they used to love. Depression is a common sign at the end of a dog's life as they lose mobility or experience pain.
Loss of Interest
Your dog may even stop responding to you or your family members entirely. A common reason dogs lose interest when they are dying is that their brain functions begin to shut down. They may experience mental confusion that causes them to appear detached.
Some dogs will know their time is approaching and will look to their people for comfort. Saying goodbye to your dog with love and grace means staying with your dog during these final hours, and reassuring them with gentle stroking and a soft voice.
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.
Once you're sure your dog has passed, the next step is to call your veterinarian's office. A vet's office will take your dog's body and either dispose of it for you or store it for you before you have a cremation or burial. They might also know of resources like a pet crematory or a mobile vet service.
Here are some examples of what not to say when a pet dies: "Don't cry." Crying is part of the grieving process for many people. "It's just a [dog/cat/etc.]." A comment like this that downplays the loss is mean and thoughtless. You don't know what the pet meant to that person.
Give them all the things they enjoy most – their favourite toys, their favourite food. You know what will make your pet feel most at ease in the time that remains. If you become tearful, ask a family member, friend or other trusted person to take care of your pet so you can leave the room and have a cry.
If your veterinary practice is arranging cremation for you then they will keep - or bring your pet's body back to, in the case of a home euthanasia, or a natural death at home - then at the veterinary practice. Your pet's body is usually picked up by the crematorium and brought to the facility in their own transport.
A 13- to 15-year-old dog, depending on her size and health, is roughly equivalent to a 70- to 115-year-old person. In her elder years, it is harder for your dog to learn new things. In fact, she likely will be resistant to changes in her surroundings and routine.
You can know if your senior dog is in pain by observing for behavior changes. Symptoms such as limping, reluctance to walking and rising, sitting, or shifting body weight to one side of the hip, are easy giveaways as far as pain is very likely involved.
In most cases, the pets turn inward. They withdraw from the people they love and no longer show any interest in what is going on around the house. At other times, dying pets seem to seek out more attention from their caretakers or do things they have never done before.
The dog's heart can't pump blood through the body very well. It leads to coughing, exhaustion, a swollen belly — and eventually, the dog's lungs will fill with fluid, and she will essentially feel as if she is drowning in her own body. We didn't want Barky to experience a terrifying, painful death.
Coughing when at rest or sleeping, excessive panting, persistent loss of appetite, a swollen belly, and pale or bluish gums are also signs associated with heart failure. The dog will develop generalized weight loss and muscle wasting due to the effects of CHF on other body systems.
There is no way to say for certain when the time is right to get a new dog. This is a very individual decision that often happens organically. Some people only wait days to weeks, possibly because they cannot bear to go long without a canine companion.
What to Expect After the Euthanasia. Once the solution has been administered, your vet will listen to your dog's heart to confirm the death. Your vet will let you know that your dog has passed on. At this time, your vet will probably step out of the room to give you a few moments alone with your dog.
Pulse and heartbeat are irregular or hard to feel or hear. Body temperature drops. Skin on their knees, feet, and hands turns a mottled bluish-purple (often in the last 24 hours) Breathing is interrupted by gasping and slows until it stops entirely.
As the solution is injected, the animal loses consciousness and within minutes the heart and lungs stop functioning. Since the pet is not conscious, they do not feel anything. Most times, the animal passes away so smoothly, that it is difficult to tell until the veterinarian listens for absence of a heartbeat.
