The bad thing about street dogs is that they pose a threat to people not because of the fact that it is mating season and they get all territorial (perhaps that's why they were fighting) and start biting ppl (especially little kids), but they also carry diseases. I actually just made my dad buy me a dog chaser because I'm scared of them after i got bit by a pack of enraged street dogs some years ago. Just be careful because as sweet as they may seem you should never trust them. There's more things I'd tell you about dogs and shelters here but I'm running out of space :)
