This past April I lost my brindle BM to cancer and it was the darkest time in my life thus far. He was wonderful and amazing and I miss him terribly still every single day.
Congrats on your BM, she is very adorable!!! I second getting her into puppy classes as soon as you can to socialize with other pups!
I agree, getting a pup (regardless of breed) at a trade fair, home show or farmer market it not an ideal circumstance BUT there is no way that I could not rescue that pup if I have the means to at the time, from someone who thinks it is a good idea to remove a pup from it's mommy at such an early age.
Sometimes the best things come out of the blue and are unexpected! Again, congrats, I look forward to seeing more pics of your brindle baby!
