At what age should one consider introducing joint supplements into the dietary regimen of a canine companion? This query often arises as pet owners strive to maintain their furry friends’ mobility and overall well-being. Is there a specific age threshold that denotes when a dog might start experiencing joint discomfort or potential vulnerabilities in bone structure? Could the breed or size of the dog influence the necessity for such supplements, with smaller breeds perhaps being less susceptible than their larger counterparts?

When should a responsible pet owner take action to safeguard their dog’s joint health?
