Does anybody know what products help with seperation anxiety. My 3 year old dachshund archie is 3 but found out the other day he howls when we are out, its mad me feel sad for him. He is on his own for around 3 to 4 hours during week. Im in middle of trying out thundershirt. It helps with his barking at other dogs but not sure on his anxiety. Any products out there any if you tried?
