Wet food shouldn't be left out longer than 20 min. - as was said earlier, it's a breeding ground for all kinds of bacterias and stuff.
I think it is safe to assume that a fly didn't lay eggs in your dog's food after it was put out for him - flys lay about 300 eggs so I imagine there would have been quite a few more maggots present. Also, it takes 24hrs for the eggs to mature to the maggot stage, so unless you had the food out for a full day...
I would take a look at the bag of dry food as well as the can of wet food, if they havent been re-sealed properly after being opened, then a fly easily could have gotten in there - contact the manufacturer as well. I don't think these maggots appeared as a result of food being left out for 8 hours or so while you were at work or something.
As far as your puppy possibly eating a few maggots... Most maggots were probably killed when he chewed them. Most of the remaining maggots probably were killed in the stomach. Those that were not killed in the stomach might be able to cause upset stomach, intestinal/abdominal cramping, diarrhea. Chances are though, that the little buggers are dead and won't hurt your pup! I would just keep an eye on him for an upset tummy. |
