Outside grey green black orange

i took 4 boys out this morning. We were out for about 30 mins playing. I had intended to take rest out but just too hot. Puppies can't regulate temp real well. And they were panting pretty hard. So I'll take rest out tonight. I posted some videos on Facebook this morning. And I'll continue to post and blog all week. As each person visits and decides I will do a blog so everyone knows who choose who. It will be a hard decision as so many boys look alike and girls look alike. This is my first ever litter that they are all so similar. Boys are light girls are dark. Boys are a little more happy go lucky. Girls are a little more dominant. Even the quite ones are dominate. Girls are a little bigger. Boys a little smaller. There are only slight differences in looks and personality. You will find all the pictures I took outside below. You should be able to tell who is who. Grey is darker. Green is bigger. Orange and black are a little harder but you can see collar in most pictures.
