We didn't have any dogs when I was growing up, so I am the newbie to the dog world. About five years ago, step-son wanted a dog, a german shorthair. We couldn't pay $300+ for one, so he started reading the ads in the local newspaper. One day, there was an ad for a litter of half german shorthair, half lab puppies, so he picked out the one with the most german shorthair markings, which was also the runt of the litter and named her Lucky. She has the classic gs markings, solid color head, ticked body with some large patches, except she is jet black and white, instead of liver and white. Since step-son was in high school sports, Lucky was lonely, so when she was about eight months old, we visited the local animal shelter and picked out a purebred german shorthair, also eight months old, and named her Sara. (they had three gs to choose from!) Up to 2 dogs.
My husband had had a brittany when he was younger and wanted another, so when an acquaintance had a litter of 11 (Wow!!), he took one of those, and named her Bailey. As much as I liked the first two dogs, that little brittany just stole my heart. When Bailey's littermate was returned to the breeder when they were 18 months old, I took her for "my" dog and named her Missy. Up to 4 dogs.
Step-daughter had been asking for a golden retriever, but we said no, four dogs are enough. One day a friend asked us if we would take her nine-month old golden because she couldn't keep him any more, so he became dog number five. Four was okay, five is overwhelming, at times. We refer to them as "the herd".
The brittanies are my favorite. And they are perfect for each other, the same age and energy level, so they wear themselves out.
