jack russels

We have a Jack Russell mix with Australian Shepherd (I know, blind date!) who is now 10 years old (he was with us since 5 weeks old) and is getting grumpy. He has some increased stress and anxiety to stormy weather and noises in general, he cannot stay in a confined spaces - otherwise generally for his age is in good health, he runs like bulett for the tennis ball and happy camper with all friendly faces, but needs us arround to be cool with strangers, not a great communicator with other dogs either.
