I had no luck with my swinging jenny. The weather in the Pee Dee area is to changing for a outside Jenny. Unless a dog is brought up running one. A lot of dogs will not run one even when bait is in front of them. Or they will get frustrated and attack the mill possibly breaking a tooth. In cold windy weather a dog will not like running a Jenny no more than you will like standing out there in it.

Track gets wet or freezes up not much you can do till it drys out. The Jenny of the larger sizes seem to work best out in more Desert type weather like Texas etc. If one had a huge and wide type Barn or building. That gets you and dog out of the weather will help a lot. Still the dog may not like working it.

Yet even a first time puppy will run a big turn table. Seems a dog or puppy likes them like a Guinea pig likes a Wheel cage. Lot of dogs do not like noisy tread mills either or the strain one can put on their back end if over done.

I still feel that some walking before after and during, along with the table to weight pull and back to the table in sets. After a dog has had a proper pre keep. Is the Cat's Meow way in my part of the country. Cheers
