My 52 pound lab (Georgia) was an intentionally chosen runt. She has fished with me for ten years. She never gets in my water, she loves fishing with multiple people (team sport!), she points at risers on the rare days I fish for trout vs. steelhead. One thing no one has mentioned is the need for a dog to be willing to cross the water; labs are strong enough swimmers and will follow when trained correctly. When I am fishing the NF Stilly or Upper Sky she always follows me across the river when I need to cross, which is a dog requirement for me. She has two flaws as a fishing dog: 1) she likes to be "involved" in landing fish, although that's never cost me landing something great and 2) she lets me know (barks) when someone else walks on the bank near me, which sometimes scares people.
