Can dogs take Tylenol for cold weather joint pain?

No; dogs are not small humans and do not react to human medications well. Over the counter pain medications for humans, like Tylenol, are actually toxic to dogs and can kill them even in small doses. If you suspect that your dog has Arthritis (joint pain), you should take your dog to your veterinarian and he/she can prescribe a pain medication that is safe for your dog to take.

You can also make it easier for your older dog to handle cold weather by providing warm blankets for him/her to lay on or providing heat to his/her resting place through the cold weather. Remember that dogs with long hair coats (German Shepherds, Golden Retrievers, etc.) will tolerate the cold much better than humans while short-coated breeds (like Chihuahuas, Boston Terriers and Boxers) will be more like humans in their reaction to cold weather.
