Hi I have a 10 month old lab and she is my world.
Unfortunately I am having to look at taking on a new job which will involve working 2-3 nights per week. I am now single so she is left alone in a crate & puppy pen complex (several puppy pens do a quite large space). With me popping home in my breaks to walk her and let her out for a wee. She has never been left for more than 4 hrs.
If I start nights I would be gone for about 12hrs but it would be time when she would normally be settled in her crate anyhow (as this is where she is overnight).
The other option would potentially be to take her with me and leave her in my car boot for couple of months if she doesn't settle (only when temps allow) I would be able to keep checking on her during the night and she would be in a locked secure car park so risk to her would be minimal.
What are people's thoughts?
