>The litter I am patiently waiting for (yet to be conceived) is between two black labradors and there is the possibility of some chocolate pups turning up in the litter. My understanding is that somewhere in the family tree there will be chocoalate labradors for this to be able to happen?
Yes.
>Is there any truth to the theory that chocolate labradors are less trainable, and if so would you steer clear of that colour?
Instead of fixating on colour, think about whether the dogs in the pedigree are working bred or show bred. The reason chocolate labs have got a bad reputation as working dogs and thought of as being not too smart and a bit ditsy, is because they were (until very recently) almost only ever bred for the show ring. It was very difficult to see chocolate dogs in the shooting field (that were not show bred dogs there for a day out) and very rare for them to see any competition success in the field.
This has all changed more recently and there are now quite a few really nice lines of chocolate working dogs coming through with some breeders making it one of their goals to bring more working ability into chocolates by breeding to field bred dogs of other colours.
So instead of thinking about whether there are any chocolate dogs in the pedigree, look at whether any dogs (of whatever colour) are working bred or show bred. What are the titles on the dogs in the pedigree? Are they show titles or working/field titles?
>The male dog is about 200 miles away is this common? It seems a long distance to travel for a dog when there are lots of labradors around
Very common for a good breeder to travel a considerable distance to find the right stud for their female dog. (Although rarely do they travel as far as Brainless LOL)
>Finally we haven't fully decided whether to have a male or female yet and would appreciate feedback on the type of companion they make.
Instead of thinking about which dog would meet your needs, I would turn it around and ask whether you will be able to meet the needs of either sex. I'm not a huge fan of neutering unless there is a clear medical or behavioural reason to do it (and let's just say there are much fewer of those reasons than the majority of vets would have you believe!).
An entire male Lab is likely to go through a slightly testosterone fuelled adolescence, which many find challenging - but if you can weather it, you will emerge out the other side into adulthood and all will be ok in the majority of cases. If you think you are going to be troubled and rush into neutering your dog at the first sign of adolescent challenging behaviour, then please don't get a male dog. Because *you* won't be best meeting *his* needs. On the other hand, bitches tend not to go through such adolescent turmoil on average - but you will have heat cycles to deal with. You will need to ensure you can keep her away from other dogs for at least 3 weeks every 6 months (on average), exercising on leash or long-line in locations where you are not going to run into other dogs. It's not difficult but requires some thought. You will also have some blood spotting on the floor to clean up, which is pretty easy if you don't have carpets, can cover the sofa with a throw, and can put rugs away for a couple of weeks. I don't find it difficult to deal with, but I do know that some of my clients are slightly ridiculous about it - and again rush out to spay their bitches at the earliest opportunity.
So please think whose entire-ty you can best manage and whose needs
you can best meet - and make your choice about sex based on that, if you don't have other dogs in your house to consider...
