ears on catch dogs

this is just honest advice nothing more and its based on 1 dog. I had a pit that i had the ears cropped on when he was a pup.......i brought him to the woods with me 3 times (east texas) and he had hell tryin to get back to me once he got into the woods a couple hundred yards.......i watched that poor dog run back and forth tryin to find me when i would call him and he couldn't pinpoint where i was at to save his life.......i had to wave my hat and make all kinds of commotion for him to see me so he could figgure out where i was and i honestly think it was because with his ears cut he couldnt make out the direction i was callin him from.......it may have just been that particular dog but because of that i never clipped ones ears again and never had problems with any other dogs.......he was a good dog but at the end of the day i want a dog that can go straight to a bay and come straight back when the job is done without having to worry about him not being able to find me
