Garden supplies that are safe?

Hi all,
 
Wasn't sure where to post this.
 
Hope everyone's having a good holiday weekend.
 
I'm wondering if anyone can offer any pet-safe suggestions for a couple of products (bigger bonus would be ones that can be purchased at a local store).
 
I live with my parents right now and was out shopping with my Dad when he went to grab some Round-up and Raid. Before I even read the label I said "No, no, no"!!! I've gotten mixed opinions from people about the safety of these products, but regardless I want to be extra cautious as my dog has a couple of liver problems.
 
Any safe suggestions for a crab-grass/weed killer, and a hornet/wasp/ant spray? (and hopefully easy to purchase - if I don't get something of my own quick, I'm afraid they may get these anyway).
 
Thanks in advance for any help....
