I'm new to having a dog so I want to be sure he's a full breed Boerboel and is he the type that will eventually grow huge in future

You really can't know just by looking at the pup. Try getting a picture of the parents or wait till the pup grows older

that's a brindle bull mastiff puppy

this one go just dey talk rubbish

Without the parents pictures you can’t know what breed or how much quality the dog has, unless you wait for the pup to grow a bit like 7months before you can tell if it’s pure or not

i go just dey talk rubbish

Without a DNA test i can’t know if the dog is my child cause I'm not such if i mated the mother or how much resemblance the dog will have with me unless i wait for the pup to grow a bit like 7months before i can tell im truly the father of the dog

OK then let's wait
