I have lots of flowers and shrubs surrounded by mulch and Chance always grabs mulch and chews it into little pieces. I don't think she tries to eat it but I am a little worried she might someday and could choke on it. Do you think it's a realistic choking hazard? I could put 1 1/2 foot high fencing that I've seen some people have to keep the dogs out. It would be a lot of work and I think it does detract from the beauty of the landscaping though.
