There is a product designed for dogs and cats to help with anxiety in the animal. Its called a Thundershirt.
Fortunately, Jaxon doesn't seem to have separation anxiety. He does have an aversion to loud noises like fireworks. We made our own version of a thunder shirt for Jaxon.
Jaxon loves playing with stuffed animals, especially ones with long arms and legs. They are easy to tie around him.
Jaxon was able to untie the monkey when he got up.
He puts up with a lot from us.
But he still loves us.
