Since I've dealt with several arthritic dogs in rescue, I have often asked myself the question: How can I exercise a dog suffering from pain related to arthritis?
Senior dogs still need daily exercise! (from here)
1. Make sure all exercise is done on a soft surface. Hard pavement and concrete can be rough on an older pup's joints. If possible, walks and playtime should be done on grass or another soft surface.
2. Try swimming... While swimming is great exercise for all dogs, it's especially good for seniors. It is relatively low-impact and keeps their joints and muscles moving without being painful. Swimming can also be very relaxing and therapeutic for your dog!
3. ...Or low-intensity games. Keep up the short walks if that's what your dog is used to, by all means, but if your older pet isn't up for a walk, consider playing some fun indoor games. Try hide and seek, fetch, or "find it" using treats or pieces of kibble.
4. Consider weight management. Even a few extra pounds can be extremely painful on your dog's inflamed joints. Exercising your senior dog and keeping him at a normal weight is a necessity, as any extra weight puts more pressure on those joints.
5. Give him a doggie massage! Pet massages are becoming more and more popular, and they are especially beneficial to those with arthritis. Not only does massage help your dog feel loved and pampered, it can also help with discomfort, poor circulation, and flexibility.
One of the most inspiring dog/human bonds ever!
