Rocky and Mesquite get a plentiful dose of grasshoppers, crickets, spiders, flies, bees and mosquitoes whenever they can hunt them down. I've never had any problems with any of those.
It's when Rocky hunts down green beans and they come out the same way they went in that I worry
That being said... I don't think I'd want to feed it to them on a regular basis. I've been known to use a grasshopper that they've really REALLY wanted as an impromptu reward for behaviours by walking, but Rocky will work for anything you have in your hand. I've rewarded him with blades of grass and he acts like it's a 10 oz sirloin!
One of the more unique questions I've seen on here, bravo
The only toys my husky has any interest in are her feeder toys, and she figured them out long ago. She has a strong prey drive, so I though something moving might keep her interest, and I know many zoos and aquariums use crickets as enrichment for their small carnivores. I wouldn't expect any of my dogs to intentionally eat more that one or two of the bugs, but I can easily see them swallowing them accidentally, so I wanted to know about any potential heath risks.
Back when I had a bunch of reptiles my dogs regularly grabbed loose crickets, mealworms and other assorted stuff. Bandit grabbed a mouse once while I was feeding the snakes. One crunch and he swallowed it.
Crickets and mealworms dont have too high of a nutritional value really. I feed them to my geckos but I have to put vitamin supplements on them so that the geckos can live off of them. Honestly I wouldnt bother.
There is absolutely nothing that could occur to your pet by feeding it mealworms or crickets. My corgi eats mealworms on the daily when I feed my ducks and she actually loves them,so much so that I have started to give her a handful as I give my ducks a handful.
