Dogs, younger dogs and puppies, eat bugs because there exciting
to chase and probably even taste alright. As my trainer once said,
when puppies aren't eating, sleeping, or pooping, they are honing
there "hunting skills".
Older dogs may also do it for fun, or perhaps out of habit. If
your dog is getting diarrhea or vomiting, talk to your vet, but
bugs almost always aren't the problem.
If you have a breed of dog such as a Lab, whp doesn't know when
to stop eating, eating insects may be very commen.
i would ask your vet if this is gping to be a problem, but until
then, don't worry to much. If the wild, dogs ate bugs too, :D.
