Wow she is adorable!! One of my fav colours.
But no the red nose is nothing to do with colour its just like saying a lab is a black nose lab.
Just something stupid breeders and un educated people say

And to whoever said they are a bad breed and you never hear about beagles well of course you don't, the media doesn't want to focus on other dog attacks. Like someone said they are a intense breed and can easily walk all over you or be inbred just like ANY breed. No effence but you've owned one beagle ( from what I'm getting) go to shelter and find one that's abused and see if they aren't aggressive. Some might not be but some will.
Pits are the most popular dog in the states and so I'm sure you can imagine they are the most abused, you get a dog who either submitts or turns aggressive and then thhat dog gets loose and you have a attack. There are lots of reasons pits attack but they are the same reasons any dog attacks.

Ok rant over..
