To everyone else, I recommend reading the question about the type of poison used, and then do your research.

I just read your source, and the way I read it even the mild poisons could possibly make a dog sick for a week. You are absolutely correct though that the original question specified a particular type of poison and the other answers replied with hearsay about poisons in general. I agree that a 70 lb dog is unlikely to be harmed by an occasional mouse that has died of one of the milder anticoagulents. But if you have the poison in the house, are dealing with a big infestation, or do the poisoning long term, then you are taking a risk with your pets and children.

I found some tips online:

I live in town, so if you live on large property or acreage where your dog runs free the following probably won't be as applicable to you. But if you have a smaller amount of property or your dogs are confined most of the time in a fenced area the following might be helpful:

Rats can find their way into your yard through digging or climbing, despite our best efforts to keep them out. There are still a few things we can do that can help with this.

1) ELIMINATE OUTDOOR FOOD: They are primarily attracted to food in your yard. This includes dropped seed from bird feeders, accessible garbage, dropped fruit and pet food.

2) ELIMINATE HIDING SPOTS: Rats don't like it out in the open and will usually just skirt your fence or other border in a hurried manner if they are just passing through. But if you have hiding spots they will be attracted to these, even perhaps die there from poison, or store food there, even nest and have babies. In my yard accessible to Bella I had a small wood pile, a garden shed open on the bottom and a few boards temporarily stored in the breezeway. That's it but that was enough. (I am in the process now of moving the wood pile to the carport where it unaccessible to any of my pets, including the cats, framing in the bottom of the garden shed and clearing out the breezeway.

3) ALTERNATIVE RAT CONTROL: Although there are supposedly "non toxic" chemically based rat poisons available on the market, these are still under suspicion as to whether or not they can harm your pet. I personally am not going to take a chance on these. However, if you have a rat problem there are non-toxic methods to control them. I encourage you to study this and find something suitable for your situation. For me, I will be purchasing several electronic rat / mouse zappers. These are essentially small boxes powered by D cell batteries. You place peanut butter inside and when they step on the area surrounding the food it delivers a shock that kills them instantly. A red light comes on when this has occurred so the box can be emptied and reset. There are other devices available, this one seems most suitable for my home since we live in town. I'll place two under the house (one at each end), one under or inside the garden shed and one in the carport.

These did not work at all for me when I tried them. I wouldn't recommend them at all.
