Looking for DC 30 or 40 collars, got a stared dog for trade

[Duval county]

Looking for some working collars for my garmin, have a dogo bird dog cross that is well started, hunts good an Is pretty rough. I got the dog as a running catch dog but was no an didn't hunt him since then till the other day I started hunting him an is a darn better dog that I thought. I don't need to get rid of him but I do need more collars. Prefer south Texas. 361-701-1045 justinmartinez814@gmail.com
