My first dog was like that. It just said mutt.

Actually I think this is a Cur. They often have light brown fur with a blackish nose and short floppy ears.

That my friend, is a good boy.

Mut. Dog breeds are a recent (last few 1000 years) invention of humans. When dogs intermingle without intervention they all end up looking like dingos basically.

The default street dog which I happened to just learn last week is called a Pariah dog.

Vira-lata caramelo

It's the mutt shape unchecked mixed breeding leads to.

Bitsa.

Bits of this, bits of that. Some call them Indian Pariah dogs but just free-roaming dog or street dog also works - they're not confined to a breed

But in EU and US, you don't really get free-roaming dogs.

It's probably not a breed. Breeds are something people, in certain countries, have artificially made and enforced in recent history. Otherwise, dogs are just dogs.

here in argentina we call them galgos, i think galgos are an actual breed but we use it to mean those kinda skinny street dogs. we also say they are "marca perro" this means their "brand" is "dog", brand is like a wordplay on the race in this case. so it would mean their race is dog, lol.

Many areas have what they call village dogs, they have a similar look for that area, but much different than a village dog in another country.

They usually have very little in the way of Standard Breed dogs DNA and are distinguishes separately from a mixed standard breed.

But because there is no breeder controlling traits they can vary a lot in appearance.

Mongrel

soi dogs in my country

unrestrained street fucking creates very mixed mongrel pups

Looks like part red bone coon hound perhaps.

Why, that's a Doggo Goodaboyis, of course!

or Standard lssue Cat but for dog, Standard lssue Dog?

I believe that's either a firulais or an askal

Mutt, or heinz 57, basically a mixed breed.
