I think although the pup in the pic, is lovely, the pink lip will sort itself out... but unfortunately as has been said before if you are after a show Boxer, that little cutie will not be up to standard..he is classed as "solid" and although there are solid classes (not so many these days ) you will be fighting a loosing battle with h/him in the show ring.
The Continent is the best place if you want to see Solids in the ring. The US , they like far to much white on a dog for my liking.
As a matter of interest , did you stipulate you wanted a show prospect , when you spoke to the breeder of these pups.because if you did and that pup is what she picked for you...sadly they are not very knowledgeable in the world of Boxers and the show ring.
I think yo have already been given plenty of advice from some of the Boxer folk on here.
I see someone has posted a good link for you, go there and have a look round, have a look at some of the Champions, you will see what is classed as a good show prospect .(markings wise)
Then it is down to colour, are you a red or brindle person (me I am a brindle person) and to be honest, getting a good show "red" prospect at the moment is like looking for rocking horse poo!!!
There are a few kennels who specialize in "reds" and there are a some fab ones in the ring at the moment.....(one I am hedging my bets on for crufts) but they are few and far between... a red has to be outstanding to do well in the ring.
Just look at the successful dogs in the ring now, most are brindle.
If you consider an older dog, remember you will be getting a "reject" (not the right word) from a breeder, one who they have run on, and has not made their expectations... for a good show dog....this does not mean, you will not have fun in the ring with said dog, it will be good enough for a novice to start with.
Go to UKBOXERDOGS, some good reputable breeders there, remember health testings.... it is important, dont listen to anyone who tells you , they dont have health problems in their dogs.... you want proof....and sadly even some of our known kennels dont heart score their dogs.
If you want PM me... I may be able to help...if not I will know some one who will.
