My dogs live a privileged life on a remote island, no collars, no leashes and the freedom to do as they please. 60 years with dogs has taught me that life is too short, and that the quality of life is always better than the quantity of years. I am their world, therefore it's my obligation to share and let them enjoy the amazing beauty of God's creation. You do you.Wait, so are we suppose to follow the animal's lead, as they know what they can handle or are we suppose to make the animal do as we want...no doubt, animals can survive a lot.
As a side note about dogs and getting wet. We have owned Chesapeake Bay Retrievers for years, a breed known for relishing getting wet no matter what the temperature. When our first dog was 12 and dock jumping at the end of October he suddenly collapsed. Some knowledgeable friends got some sugary treats into his mouth pronto and he came around. I did some research and found out that most mammals are able to shake their coats of water at the perfect velocity to dry them -- but, as animals age, they lose some of this ability. Our Argus had DM and we did not realize that it was effecting his shaking to such a degree that he went into shock from hypothermia that day.
Always monitor your dogs as they get older (and your chickens, too), because things that they could thrive through just the previous year could be too much for them as they continue to age.
