There is not an official age that a dog becomes a senior; this is something that the Poodle's veterinarian will discuss with you as your dog is aging.
In general, smaller dogs live slightly longer lives than larger ones; they age a bit slower and for this reason Toy Poodles and Minis are often declared to be a senior by the 8 or 9 year old mark. Standard Poodles become seniors earlier, often by the 7 year old mark.
Even if the vet does not make an official announcement, any dog that is at least 9 years old will be considered to be in his or her senior years. This does not mean that your Poodle will suddenly be old. Rather, it is a slow process and being declared a senior will mean that the dog should begin to have geriatric screenings twice per year (to check for common health issues that occur with older dogs) and that there should be some changes in regard to care.
Ahead we will look at some of the common signs of aging and what to expect with your senior Poodle.
