Sup, my homey Otis! Word up, Yoda says! Mad props for gettin' the rents to getcha yer OWN yard! Yay!
Looks like 48 hours is a good amount of time to let dogs back in the yard after spraying the area for regular weed killer. There's also organic weed killer which says 30 minutes or you can try vinegar or hot water. But of course I'd like double or triple the time they say, just to be safe... Here's some stuff I found.

Q: When is it safe for children, pets, and horses to enter the treated area?
A: If this product is applied to crops listed on the label on farms or sod farms and in forests, the restricted-entry interval is 48 hours. See the Agricultural Use Requirements on the container label for specific requirements regarding early entry into treated areas. For livestock re-entry, hold animals out until the spray has dried. For lawn and turfgrass applications, hold people and pets out of the treated areas until the spray has dried.

DEADEYE Organic Weed Killer works by dehydrating the weed or grass, burning it from the top down. Results in the form of browning and wilting, are visible within an hour in full-sun applications. It is safe for children and pets to enter the treated area as soon as the product has dried, usually within thirty minutes.

Another user suggested using boiling water to kill weeds. While it does work, it's also costly in energy use & can take a lot of going back & forth to the stove to do a good job.
Vinegar makes a great weed killer. It has to be used properly to do the job but that's true of almost anything. And it is very safe - endorsed by organic gardeners & used by railway companies to kill vegetation along rail lines that would cover tracks.
Ordinary strength vinegar (5-6% acetic acid) is used. To a gallon of vinegar, one would add a 1/2 tsp of dish detergent to act as a surfactant so the vinegar would penetrate the soil well & move down the root. Put the vinegar into a large squeeze bottle (for a small job). For larger jobs, use a garden sprayer that will deliver a thin stream instead of a wide spray.
You need to trim off leaves of weeds that cover the root (like dandelions, plantain, & other low growing weeds) but if the leaves aren't in the way, don't worry. Just make sure you aim the vinegar stream down to the ground & just around the root. It will penetrate & the weed will die in a day or two. If you spray it around, the grass or other plants will die too. It's best not to use in a mixed bed where you don't want to harm other plants.
The vinegar kills the weeds by disrupting the normal pH around the root but is quickly washed out after a rain or if one waters the lawn well. After a rain or two, one can reseed the bare patches with no harm. Pets & children will not be harmed by using vinegar & likely would stay away from the spots 'cause of the vinegary smell. Railway companies use a MUCH stronger concentration - 20% solution but at that strength, it can be dangerous to handle so don't try looking for a stronger concentration.
One more important thing - do this on a SUNNY HOT day for best effects. If you try it during cool or wet weather, your results will be poor. It needs a few days of hot weather to do the best job.

Q: Could you please recommend a weed killer that is safe to use where children and pets play?

A: Roger Cook replies: I can't recommend a specific product, but I do have some suggestions for you so you don't have to use a large amount of weed killer. Remember that the stronger your lawn is, the fewer weeds you'll have to deal with in the first place. Fertilizing properly, adding lime to control acidity, mowing to the correct height, and watering and aerating regularly will all promote a stronger lawn. Pruning or removing trees to promote more sunlight is also important.
If you are going to use a weed control, talk to your local garden center. Find someone knowledgeable about weed control chemicals and have him or her go over the label with you. With a granular formula, the whole yard is covered. To cut down on the amount of weed killer you will need, consider a liquid instead. You can put it into a small sprayer and walk the yard with it, spraying only the areas that need it. Whether you use a granular or liquid formula, always wear protective clothing and rubber boots when you do the application, carefully follow the directions on the container, and keep children and pets off the treated area for 48 hours.
Keep in mind that a few weeds won't ruin your lawn. We all have a picture in our minds of the "perfect" lawn. I think we should redefine the "perfect" lawn as a lawn that is useable and chemical-free, where we use as little fertilizer and water as possible to achieve this "new" look.

On weekend mornings in the summer my two dogs and I often awake to a symphony of lawnmowers, weedwhackers, and roto-tillers. People hard at work in their yards and gardens now will soon enjoy delicious tomatoes, beautiful blooming gardens, and deep-green lawns.
Just last weekend my parents came by to help me in my garden. And along with several garden tools, my Dad brought the weed killer. My Mom and I shared a knowing glance. With my two dogs, who begrudgingly share their backyard space with a vegetable garden in summertime, it can be hazardous to use weed killers and fertilizers. Or so I thought. So we used elbow grease instead of herbicides to battle the dandelions.
However, for pet owners who want to spruce up their yards and prefer to use lawn care products, reading the label and using the products properly is the key to keeping pets safe. According to Dr. Petra Volmer, veterinarian and toxicologist at the University of Illinois College of Veterinary Medicine in Urbana, problems usually arise only when people apply lawn care products incorrectly or when a pet is accidentally sprayed or allowed on a freshly
sprayed lawn too soon.
Most lawn care products fall into three categories: fertilizers, insecticides, and herbicides. "If you use these products correctly and read the label, most really do not cause a problem," says Dr. Volmer. "In general, most residential-use products have low toxicity."
But everybody makes mistakes. According to Dr. Volmer, it isn't unheard of for a person to grab a bottle of herbicide instead of the flea spray and accidentally douse the cat. "With these yard products, any direct exposure can be a problem," says Dr. Volmer. "If you find your pet rolling or walking in a recently sprayed area or spray him by accident, immediately wash the substance off with a mild dish soap, such as Dawn, and contact a veterinarian."
Dr. Volmer notes that insecticides tend to be more toxic to pets than herbicides or fertilizers. "There are a few insecticides for use in the garden, especially those for roses and molluscicides for snails, that can be very toxic. People need to be especially careful with these products around animals."
Your pets will thank you for following instructions and using common sense with lawn care products. So, put your animal in a safe place, away from the area of application. Store all fertilizers, insecticides, and herbicides where pets cannot gain access. Keep all products in the original container and make sure the label is intact and readable before using. Then, always read the label and follow directions exactly. And finally, make sure a treated lawn is
completely dry after waiting the maximum period recommended on the label. To be extra safe, consider watering down the lawn after application and letting it dry before allowing pets into the area.
If you notice your dog or cat acting strangely, stumbling, salivating, vomiting, or having seizures and especially if you have recently applied a lawn care product, call your veterinarian or the American Society for the Prevention of Cruelty to Animals (ASPCA) National Animal Poison Control Center (1-888-4 ANI-HELP) immediately. Don't forget to have the product in hand so you can tell a veterinarian what chemical your pet may have
been exposed to.
For the latest information and advice about the pet-friendliness of specific lawn care products and less toxic alternatives, consult your veterinarian or the ASPCA National Animal Poison Control Center.
