Take what I am saying as just another hunter, not as a vet or anything. In theory, the standard corn syrup (not high fructose corn syrup) should be pretty much all glucose and will spike blood sugar and cause a large insulin release if given when the dog isn't exercising. However, if given part way into the hunt, it should go more directly to the muscles instead of being stored as fat. It is replenishing the stores rather than being converted to fat (what would happen if the dog wasn't exercising when consuming it). In theory, I think it shuts down the ability for the dog's body to burn fat, and the large insulin spike could cause a rebound of hypoglycemia in the blood (low blood sugar).
With honey being a mix of glucose and fructose, the insulin response is lower, and the dog's body continues to burn fat at the same time as the glucose. The fructose goes through the liver and is converted to glucose, giving a slow drip of glucose to be used over a longer period of time.
I give bees honey to my dog (who happens to be named Honey) once in cold weather during hunts and once right at the end of those hunts. I may also give it to her at the end of a not so cold weather hunt if we are hunting more than 2 days in a row.
The reason for giving it during hunts is because she is burning a ton of extra energy maintaining her body temperature (short coat) when it is cold and/or cold and wet. In those conditions, they just can't convert fat to energy fast enough and use up the glycogen stores in the muscles faster too. Dogs that cover a lot of ground and are hunting all day are running marathons or multiple marathons (GPS collar distances are inaccurate due to limitations in the technology..they are running much farther than what those totals show).
The reason I give her some at the end of the hunt (should be within 30 minutes of stopping) is because it will go directly to the muscles to replenish the glycogen stores, so she is ready for the next day. It also does something to aid in other aspects of recovery. Body builders used to do that too. Now they might use something like maltodextrin, which is again pure glucose, just in a form that doesn't cause as big of an insulin spike.
Was that in cold weather or warm weather? Is she on a high fat dog food diet?
So the sildenafil is dissolved in the water too?
Sounds like you have it figured out! What breed is she?
