This is Arthas S divokou krví (translated: Arthas with wild blood). He's about 2.5 months old. We temporarily care about him, his final home will be in Colombia.

Our regular dog, Esta (9 years old female) is enjoying his stay, as well as my daughter (about 2 yo). The only one mad here is my GF and her sense of order and cleanliness.

He's a little rascal, but can be very cute, when he wants. See more pictures of him and Esta here: http://gallery.rider.cz/Esta/20130107_Arthas/

Both Arthas and Esta are Czechoslovak wolfdog, so they are technically about 25% of wolf.
