I am a recent owner of a King Charles Spaniel. He is 5 months old. I will be getting back to work next week. He is potty trained. At night, he sleeps in his crate. Because I am still on vacation and me being home, I let him out of the crate. He stays the longest in the daytime for 3 hours while i do work around the house. He does cry/bark. And I fall to his cry and let him out. How should i prepare him when I am back to work? Or prepare him for that long stay in his crate. I should be home from work for about 6 hours. Please advise. He still is learning to how to go into his crate freely. And we plan to bring him next week for puppy training class.
