Age of the Dog:
A senior dog often makes a great companion for a senior human — they may already be trained, and they are usually less active and demanding than a puppy. Another age-related consideration is a dog’s overall life expectancy; small dogs generally live longer than large ones.
The temperament of a dog (and how it meshes with the owner’s temperament) is extremely individual, even taking breed into account. Any potential dog owner will want to take the opportunity to interact and play with an animal before deciding if it’s a match made in dog heaven.
Owner’s Medical Needs:
Consider carefully your own physical limitations. If you have mobility issues, will this pose a problem for a dog that needs daily walks? Do you have oxygen tubing, which might present a playful puppy with the temptation to chew?
What resources are available to help care for the dog, in the event the owner is not fully able to handle the responsibility? Can you afford to pay for grooming, veterinary visits, supplies, or pet sitting when you’re traveling? What resources are provided by the assisted living community? Do they have a Pet Care Coordinator?
