TV vet Charles Bagnall has given tips on how pet owners can reduce the symptoms of dog arthritis.
The 'vet of the year' finalist responded to a Sun reader whose pet boxer cross has been limping after exercise.
He told the news provider that this could be dog arthritis, which can be treated through pet medication.
"There are several things you can do to try and reduce the problem; care with exercise, do not overdo it, little and often rather than one long walk, keep weight down and consider joint supplements," Mr Bagnall is quoted as saying.
Joint supplements that have been recommended include glucosamine and chondroitin rather than cod liver oil.
If the problem gets any worse then the owner should take the animal to their vet.
Mr Bagnall has been a partner of the Orwell Veterinary Group since 1994. He has his own black Labrador called Spud and a cat called Billy.
