My dog Foxy LOVES Maggie, a dog we have been watching in the afternoon while the other dog she lives with gets a much longer walk. She's not able to walk very far these days, so she gets her walk down to our house and then my daughter plays with her until her owner and Amos (the other dog of their house) return.
My dog Foxy on the right can't stop nuzzling with Maggie, licking her, and rolling on her back to show her how much she looooooooooves her. It's very cute. And every once in a while, Maggie will tell her to "cut it out kid!"
I caught this with my nifty fifty in awful light, so when in doubt, go black and white! Radial filter to bring out clarity of Maggie (on left) as depth of field was not going to do anything for poor Foxy writhing on the floor in pure JOY. Capturing Joy in June! Missed a shot yesterday, so will find a filler I think (or technically I did take a stupid shot on my phone, but it's got no joy in it). :)
