I have an 8yr old Australian Cattle Dog, over the last year he become rather inactive. When we go on hikes, walks or jogs he turns around to go home after about 10-30 mins. He has never had interest in playing with other dogs, we have gone to the dog park his whole life, he just sniffs around for a bit then stands next to me, I still take him since he likes to sniff. He has many toys he loves but only wants to play if someone besides me is there to watch him. He will play fetch with a stick a few times then stop unless someone besides me is cheering him on with that as well. I feel like he is bored but I don't know what to do for him so he will get the exercise and stimulation he needs. Currently the only things that seem to excite him are squirrels and lizards, which he has always loved, but those don't really help him with exercise. If anyone has suggestions for what their dog enjoys I would love to hear. Thank you!
