Not really. Gators won't eat below 60 degrees because they can't digest and would rot from the inside. I did some research on it and came to that end.
That said, if an area is covered in Gators the temp wouldn't matter as much, I'd leave the dog behind. A reactive gator bite will kill a dog even if the gator doesn't plan to eat. I took my dog to Butler once and probably wouldn't do that again unless it was downright cold for S GA like sub 40s.
Up here near Hilton Head gator took a woman walking her dog a couple of years ago.I will give a different viewpoint. I hunt ducks in central and south Florida. I have always had a retriever. It really depends on the situation. Most of the places I hunt the gators are real skittish since they are hunted for a couple months before duck season but I will not take my dog if it is deep, and I mean over knee deep or so. Gators big and brave enough to take a dog almost always have deep water nearby, and I won't hunt a dog in that situation, any temperature. Areas with large expanses of shallow water are best, and the dog must mind and be able to be called back at any time. IMO
Shirt pocket full of steel 2 3/4” #7s keeps them at bay.
Gil you and I hunted allot of the same areas in the past you and I know it gets worse every year.Years ago a friend's cousin was duck hunting the Savannah River below Augusta and let his dog out while putting his boat in the river. He couldn't find his dog and shined his Q-Beam in the water and saw a gator moving away with his dog between his jaws.
I second what is said about the behavior of gators. I wouldn't want my dog and I to appear in Ripley's Believe it or Not about losing a dog to a wintertime gator. Gil
I hunted the central FL section of the St Johns River for 2 decades. I know all about that. I stopped hunting a dog on that water loooong before I moved out of there. Scary how quick they come out of nowhere. I’ve stepped on them wading in twice in that time. The #7’s will keep them from your dead ducks before you get to them. ??It`ll happen so fast you won`t have time to hardly react before it`s too late.
