Hi I am a mother of 1yr old chihuahua. I have a query over what you guys do when you leave chi alone at home. When he was a pup I use to leave him in a crate so he doesn't injure himself as well as demolish the place. But this was no longer than 4-5 hrs. But now I've got a new job I may have to leave him for longer than that on some days. I am terrified of leaving him alone (just in case he develops separation anxiety) but also I am not sure where to leave him. If I do leave him outside crate would he injure himself by chewing electricity cordes or damage the whole house? Also I recently bought play pen for him and left him in there for few minutes to see how he finds it but he climbed out of it anyway..Hmm not very useful.. Anyhow any contribution from your experience will be so valuable. As he is my first dog and books don't teach some aspect of raising him.
