Acting a bit weird...

Since Sunday, Louie has been acting a little weird. The other day he was annoyingly trying to get me to play every 5 minutes despite already being playing with him for an hour.. today he's subdued..

I have a few reasons why but I'm not sure on any of them.

1. Could be that I have been walking him on a decent medium walk everyday (he used to get some short, some long and then some that would mean we were out for hours - but not everyday) but this wouldn't explain the over eagerness to play..

2. I have had him on raw food since Sunday (instead of the once/twice a week he's used to) this could explain the energy.. (apart from last night - he only had biscuits after training! Could explain his lack of interest this morning) Plus I have seen an improvement in his coat, it has more shine to it.. too bad he'll be on dry next week, didn't have enough money or freezer space and the supplier only delivers every month...

3. I'm thinking it could be the weather.

and 4th. I'm in a mellow mood today - so he could be picking it up from me..

Any ideas - or am I worrying too much..
