Oh dear - 'This name is invalid' - I really thought that you had finally made up all your minds and decided on a Lab and all you had to do was find a good breeder - and then get the pup !
Labs are what is classed as a gun dog breed as is vizslas and the breed I love - GSPs - German short-haired pointers.
Have you ever been to a show to see any of the dogs that you have said that the family have liked the look of ?
All breeds of dogs can and will be very different in nature and ability - and this can happen in the same breed. Just doing internet searches and asking on forums - is the first step in looking for a pup - not the only way to find a pup that you would like to live with for 10 or more years ! If you are lucky !
So what I would suggest to you and your family at this stage is to do the following - which should have been done right at the beginning of your quest for a pup - if you all are looking now at a pure breed pup:
1. Do up a list of what you want in a dog - for example - what size, shape, looks, fur type, nature (though a lot of that is to do with training), health and anything else you can think of,
2. Then the next list you need to make up is what you can offer a pup. I feel this is the most important list - because if you are really honest - you will find a lot of the breeds you have looked at are maybe unsatisfactory.
3. After these lists are drawn up - then I would be off seeing the pups at the shows - and talking face to face to heaps of breeders. You can always come home after the shows and look up the different breeders on line and/or do internet searches. There is heaps of information out there. But - nothing beats meeting the dogs and breeders - face to face !
So - homework, research - is really important - particularly when you are trying to satisfy different family members !
