The first and the third look like Russula sp. https://www.google.ca/search?q=russula&source=lnms&tbm=isch&sa=X&ved=0ahUKEwio2s3A4ofjAhVps1QKHU36DxEQ_AUIECgB&biw=1521&bih=672

If you have a concern about the dog eating them, just remove. There are way too many different fungal species to be able to ID 99% with any certainty and the vast majority are nonedible and even toxic. But most are harmless in the ground

I agree that the one and three look like Russulas. The second looks like a Bolete. If if has spongy tubes rather than gills on the underside, it's almost certainly a bolete. As a rule, Boletes are edible if cooked and:

1) they don't stain blue on cutting and

2) they don't have a red or orange pore surface (the spongy underside where gills would be if the mushroom has gills).

There's a bitter bolete that no one knows if is edible or not, as it's so bitter people spit it out. Some people have stomach upsets in response to 'edible' boletes and the inedible ones can make you miserably sick for several days, but you are quite likely to recover fully.

Some Russulas are edible, but there are lethally poisonous mushrooms that look similar to many Russulas, so most amateur mushroom hunters avoid them.

Mushrooms are so wonderfully varied, it's fun to look them up. I like the Audobon Field Guide to Mushrooms.
