Well I've gotten some really great suggestions both here and on other forums (although you guys were SO much nicer
) so we've been working on that.. he has been better! We are making a conscious effort to walk every day (if we can) and/or have some really stimulating playtime. We also have been feeding more. I've seen some slight improvements so we're taking it one day at a time! I haven't been nearly as frustrated as I was when I posted that. I'm thinking it was a phase that's slowly going away.
Also we did find a ton of flea poop/fleas on him that I think he got from daycare (ick I know!). And while the behavior started before he went to daycare I think maybe some of the drastic parts of his behavior can be attributed to that. We have since bathed in Dawn and used Frontline Spray.. hopefully we got all of them.
Thanks for all of your help and I will keep you updated!
