I'm sure I'm just over reacting and it's nothing but here's what I've noticed in the past couple of days.

Kit is no longer interested in sleeping on his bed or lounging on it. He sometimes takes a treat or toy onto it, but he's usually lounging or sleeping on the tiled kitchen floor. And most recently he's been sleeping by the front door, it has the coldest floors in the house due to the spacing between the front door and ground. He finished shedding (for the most part) recently. So could the mid 60s to low 70s house temp be too warm for him?

Another thing that started most recently was that he no longer dives for his food. A lil history. He's been on Iam's puppy formula before I got him at 4 months old. I switched him between some kibble foods and he started to have the runs (about a week after I got him). I then went to raw (Stella and Chewy Chicken) food which didn't really fix his stool problem (would sometimes get so bad he would make a mess in his crate). I then took him to the vet, got some powder to mix into his food, that didn't work. So he prescribed some pills (don't have it in front of me) and had me buy the Hill's Scientific Formula W/D (yep, i know it's bad, keep reading faithful...umm.. reader) so after browsing on here for a bit, i discovered how horrible the scientific formula is. After his stool hardened and there was no more messes in his crate or uncontrollable indoor messes, i stopped the pills and started to mix Hill's and Fromm and then later got Blue Buffalo puppy formula (since i couldn't make it out in time to the specialty store where i got Fromm).

At this point he was still chomping away at his food the second it came down, and by the time i finished putting everything away he'd be done with his meal. Then after he's been on the Hill's/Blue Buffalo mix for a week or two, he started to lose interest in his food and wouldn't touch it after I placed it down. He'd come back to it throughout the day and nibble at it, usually finishing 80-90% of his normal intake. I went back to a specialty dog boutique that sold the raw and Fromm food and has many other great products. I picked up the top of the shelf dog food they have their being Orijen and started to mix it with Hill's and Buffalo...still didn't really care for his food....then took out Hill's completely and now its a Blue Buffalo and Orijen mix... still... doesn't care about his food as much as he used to. Nothings really changed in regards to his behavior, he's still running around outside and being playful, but he's losing interest in his food. I'm feeding him twice a day, morning and dinner. He basically doesn't touch his morning food anymore, and then gets crated. When my friend comes in to take him out, I believe he eats up half of it, then when I come home and take him out, he comes back and eats the other half and then I fill the bowl back up with his dinner which he might have a few bites of and then progressively nibbles at it throughout the night leaving the bowl 10% full or empty by bed time. Sorry for the long long ramble, but just thought every detail matters.

Is he just getting bored with his kibble? Should I start mixing in some canned food with the kibble? What if he treats the kibble and canned food the same as just the kibble?

Your help is greatly appreciated, I'm worried about the lil guy.
