Salt the earth. Doesn't last forever, but longer than anything else I've tried. Literally a box of table salt in a sprayer mixed with water. I have no idea what to dilute it to though, maybe if it's strong enough, it'll be permenant.

Straight White Vinegar mixed with salt and dish soap all in a spray bottle will kill pretty much any vegetation (non-selective) in 1-2 days without harming your dog. It isn't permanent but it'll last a little while. It's also dirt cheap with 4L of vinegar costing less than $2.
You need to use the powerful stuff if you want to also keep that soil from growing anything else - you can buy localized products from RoundUp (and all similar brands) that don't leech into neighboring roots, but I am not sure about pet safety.
If it's not a huge area I would just use the home-made solution I mentioned above and go spray it whenever you notice weeds popping up.
You can buy lots of organic and pet-friendly labeled products too but I don't think they are any better than the home-made solutions - most of the "pet safe" off the shelf variants I've seen are just vinegar with a higher concentration of acetic acid (20%) instead of the usual 5% or so.
Thanks guys, I'll give the vinegar method a try
$60 bucks a visit. They come 5 times in total for the season. I was told this many visits wasnt needed and seeing my lawn I now understand why. I picked a company from google that answered my call when I reached out... didnt really put much thought into it other then I'm not dealing with weeds this year.
But if you spend $50 on seeds, $50 on fertilizers and however much on items to kill weeds. It's the same price or cheaper(if you value your time) to have a company come and take care of it all.
I used round up on my lawn to kill weeds 2 years ago and it turned my lawn brown for the entire year. Whoops!!
You should be able to find it in Calgary at industrial agriculture stores (UFA?). If not you can purchase RoundUp Super Concentrate at most big box stores, it will do the exact same thing. https://www.homedepot.ca/product/rou...1-l/1001190557
I let my backyard lawn die off over the summer, only thing I did with it is hit it with Round Up a few times. A week ago I spread some fertilizer and gypsum and have been watering it everyday to encourage weed growth, only to nuke them all again with more Round Up. Did some leveling and rock removal today. Planning to seed in a week or two after some more leveling work. This is our second year at this house and the previous owners were in their 70/80's and both front and backyards looked really rough.

Did another treatment of Roundup on Sunday, leveling, and rock removal. On Monday I spread seed and rolled it in:

After that I added starter fertilizer and sprayed with Tenacity pre-emergent herbicide. Then covered with 6 bags of peat moss. Now we water 3 times a day and pray.

Now onto the front yard, going to kill some weeds, crab grass, dethatch and overseed.
Just cut my lawn this morning, still looking thick and healthy. Such a mild summer this year, barely had to water.

Front side looks good too.

Nothing better then a cold beer after some yard work.

Get that fertilizer down, food for the winter:
"Fall is the time when cool-season grasses recover from summer stresses such as drought, heat, and disease. If the lawn has been properly fertilized in the late summer and fall, turfgrass can begin to store carbohydrate reserves in the stems, rhizomes, and stolons. These carbohydrate reserves help grass resist winter injury and disease, and serve as a source of energy for root and shoot growth the following spring. Late fall fertilization will also provide better winter color, enhanced spring green-up and increased rooting."

"Principles of Late-Season Fertilization
Nitrogen is taken up by the roots even though shoot growth has ceased. This is because roots remain active at cooler temperatures than shoots.
Nitrogen enhances fall colour and hence increases chlorophyll content.
Increased chlorophyll content means increased photosynthesis.
Increased photosynthesis means increased sugars. Since turf is not growing at the time of the fertilizer application, the sugars that are produced are not used for growth but are stored to enhance winter survival and spring recovery.
These sugars make the grass plant less susceptible to freezing. A good analogy is that a bottle of juice in the freezer will take longer to freeze than a bottle of water. The grass plant cells are full of sugars and hence take longer to freeze, and freeze at lower temperatures.
Late-season nitrogen applications promote deep rooting during the fall, so plants go into the spring and summer with deeper, healthier roots.
Spring green-up is early, because the nitrogen that is stored in the roots is ready when shoot growth resumes."

Got mine down yesterday and since this is a first, I'm excited to see how it works next year.
Is there a place that sells more premium grass seed that I can overseed with? I want a blend that has way higher% of whatever the fancier species is (can never remember...)
I've heard people getting the more premium seeds from Eagle lake landscaping https://eaglelakelandscape.com/turfg...s-seed-blends/
I think you might be pushing it late for a successful overseed. Kentucky Bluegrass is very slow to germinate, 2-5 weeks http://www.bluegrasses.com/seeding/index.html
