Cuteness overload xD I love the change of perspective! :D It makes me happy to see dogs (and cats) get along.
We have way too many strays here, 3 dogs and 4 cats I see regularly and feed whenever I have leftovers. (I only buy animal food for kittens and puppies when I can) Few dogs I've seen are territorial.
I kind of trained the two not growl (3rd one is the most peaceful doggy) at other dogs and cats, at least when I'm around. When I stomp and say "no" they know that it's not ok to bark :P and that I'll feed another stray instead (I wish I had more to give, but tight on money) and there are insanely many strays. Some doggies (and cats) are so sweet and friendly (I'm sure they used to be pets). It's amazing to see all the variety of personalities. Sadly I avoid touching strays as I get bad rashes instantly, even though some of them want to be petted very much.
I love this post and I hope you make a similar one again :)
