Some sort of mushroom?

Hi everyone, I've noticed this in the garden this morning. I just wanted to know if it should be removed. I don't mind if not it's just with having a very inquisitive puppy I could do with avoiding any issues. Its around 2 inches high and 4 inches wide.
Thanks in advance

 

Think I'd get rid of if you have a young pup.
It's a shaggy some thing or other.

 

That's all I needed to know thanks @pete

 

Possibly Lepiota rhacodes var; hortensis. of the 'Shaggy' type. All edible, but can cause gastric upsets.

 

Thank you @Mike Allen it won't be accompanying my bacon and eggs

 

Puffball? If you let it mature and then stomp on it it will blow all the spores like a bag of burst black flour. Great fun

 

I'll remember that @Selleri
