They might be too long and are bothering him. Check them out and see if they need a trim.

She might have sensitive skin, allergies, or hot spots. Try washing her with a dog oatmeal shampoo. If it gets worse, take her to the vet and they can prescribe medication.

It might be a territorial thing. Try getting a stand for the water so it's not high enough for him to pee in.

Some dogs are curious and like to eat a lot of different things. Eating June bugs won't hurt them. He just must enjoy the taste or has fun catching them!

In my experience, it is usually due to the fact that they are not feeling well. Every dog I have taken care of or have owned that has eaten grass has usually vomited soon after or pooped it out.

Usually try not to let them eat the grass if possible as well because you don't know what kind of pesticides could have been sprayed
