Mobility aids, such as harnesses, ramps, and dog wheelchairs, can greatly benefit senior dogs by supporting their physical activity. These tools help alleviate strain on joints and muscles, allowing older dogs to move with more ease and comfort, even if they suffer from arthritis or other age-related conditions. By using aids like ramps to navigate stairs or wheelchairs for dogs with limited mobility, pets can remain active without causing further discomfort. This promotes their overall health, reduces pain, and improves their quality of life as they age.
