If your dog is up for it, aim for two 30-minute walks per day. Let your senior pup designate your pace.

The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Sudden changes in your dog's behavior can indicate serious health issues. If your dog is in pain, has a limp, or is unable to rise, these symptoms require further investigation. Difficulty breathing, refusing food or water, or being unable to get up to eliminate are major signs. Loss of balance is also important.
2) Stops Eating/Drinking
If your dog is at this point, you can offer them the tastiest treat imaginable and they will not eat it. They will also stop drinking water. This is due to the beginning of their organs shutting down. They no longer have the sensation of hunger or thirst.
Quality of life is the key issue. If your dog is unable to function in a way that assures you that he is still enjoying a good quality of life, then it's time to seriously consider releasing him from his body.
Cancer causes approximately half of the deaths in dogs over the age of 10. “Cancer” is actually a blanked term for a collection of related disease, and each has a unique prognosis. Cancer occurs when there is an uncontrolled division of abnormal cells which spread into the surrounding tissue.

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.
12 Things You Must Avoid When Living With a Senior Dog Caring for your furry friend in their older age
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.

"Silent killer" in dogs usually refers to deadly diseases that progress with few early symptoms, primarily Heartworm, Hemangiosarcoma (a type of cancer), and sometimes Leptospirosis or Canine Parvovirus, all characterized by vague initial signs, rapid progression, and severe organ damage, making prevention and early detection crucial.
Sleep changes
Sometimes you may notice senior dog anxiety at night, including pacing, panting, whining, or barking. Or you might wake up to a furry face breathing near yours or the sound of ceaseless tag-jingling. For dog parents, the loss of sleep seems to be one of the hardest aspects of sundowning to deal with.
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles.
