I have had Snickers (papillon from a shelter maybe 7-9years old) for over 4 years. The last few months she has started barking when shes very excited like before leaving or before a walk. She is a very nervous dog and doesn't like anybody (except me thankfully) I would like to think I she is just gaining confidence and enjoying life but it's starting to be a nucianse. I try to ignore it when I can but when I cant I pick her up to avoid her starting like super early in the morning. Any suggestions?
