My family got a Bichon Frise about 3 weeks ago while my kids were on Spring Break. They played with the dog the whole time and he was never placed in his crate. Now that they are back in school, he's with me all day (as I work from home) and he always wants to play. He cries because he knows that everyone else is out the house and when I have to leave (to run some errands), he hates going into his crate. If I put him in the crate, I can almost guarantee that he'll vomit and be crying when I get back. I've tried putting toys and articles of clothing with my scent in hopes of keeping him calm but that's not helping. I've also tried crating him while I was home for short periods of time but that yields the same results. I know this is all my doing because I didn't start the crating process as soon as we got him and now he's becoming conditioned to not being in the crate. Is this something that I can correct? He's now 13 weeks old, is it too late? Please help! This is my family's first dog ever, so we're all new to this. Thanks.
