0-0-7 Prodiamine Granular Pre-Emergent Herbicide

Yard Mastery 0-0-7 Prodiamine is a granular pre-emergent designed to stop weeds in the lawn, such as crabgrass, poa annua, bittercress, chickweed, and henbit. It’s the same active ingredient the pros use, formulated for easy DIY application.

Most DIYers use this Prodiamine in the spring to stop crabgrass. Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, and then, towards late fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grass weed.

The good news is that crabgrass can be stopped effectively using this product. The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55°F to 70°F. This will give you approximately 3 months of pre-emergence protection.

My Dog's All-Time Favorite Toy
Color: Pink, Style: Grunt Sound
The first one of these I ever got her was at Petco on sale for $1 - best $1 ever! The reviews are right, though. The toy doesn't last forever and it's not good for aggressive chewers. In my opinion, however, that doesn't make it a bad toy. Here's why: Aggressive chewers comments: Getting my sister's French Bulldog a stuffed toy (that's shredded in 5 minutes), compared to my Pitbull who does not tear up any toys, but is a stronger chewer when it comes to bones. My pup does not tear this up at all, but my sister's dog would. My point is: Don't get your dog a soft toy if your dog ruins soft toys. Regarding the not long-lasting comments: the honking noise mechanism inside eventually pops inside the hole, rendering it honkless. Ours lasted about 6 months. It's pretty much impossible to fix unless you want to trouble yourself to fix it for 1 good honk each fix. I would, but I do also have a job to get to. My dog does still carry it around in it's noiseless state, but she doesn't play with it with the same enthusiasm. How did I resolve this? I bought her 5 😂 She's only on her second, but I decided to stock it because they were on sale for $5.10 - I don't think I will get rid of any of them. I will just let her play with them on rotation until they fall apart. Besides all that, my dog just simply loves this toy. I have never seen her so happy & playful with a toy. I can't promise this for your dog, as I can only tell you about mine. We even have a "Sheepy" song. [I have not been paid or given free Sheeps - my Sweet Pea just really loves her Sheepy]

Loud! Just Like She Likes It
Color: Hedgehog, Style: Big Squeak Hedgehog
My Great Dane loves this noisy toy. She prefers squeaky toys with loud, unusual squeakers. (I need to invest in earplugs.) She's not an agressuve chewer or rough player so this should last a long time. Like most squeaky toys she has, the squeaker wears out before the physical toy does and once the noise is gone she won't play with it any more. If others have a similar issue...check with your local animal shelter. Some (not all) will disinfect used toys for the dogs in their care.

Fun while it lasts…
Color: Pink, Style: Grunt Sound
Fun while it lasts. Doesn’t last very long. This is our third one and last maybe a few weeks. The part that makes noise comes detached inside which causes to toy to no longer make noise, but also can be dangerous if it comes out.

Great alternative to the grunting pigs!
Color: Pink, Style: Grunt Sound
We go through A LOT of dog toys at my dog based business. The grunting pigs are super cute, but they are also super fragile. It is incredibly easy to dislodge the squeaker. (Grunter?) These are certainly not robust chew toys, but the squeaker is about 30% better at staying put than that of the pigs. It's also smaller, so it's easier for the smaller dogs to play with. These are a new favorite! Update: August, 2024 I bought an orange hedgehog. Amazon won't let me review that separately so I had to add to my sheep review. The orange hedgehog is only 3 stars. It is made of a harder plastic than the bear and the sheep. It also has a standard squeaker, not the grunting of the bear and sheep. But harder plastic DOES NOT mean that it will withstand an aggressive chewer! If your dog likes to "kill the squeaker" they will be able to do so in minutes! This IS NOT a chew toy! If you are looking for a toy for an aggressive chewer, look at the Orbeez line from Outward Hound. The other thing that makes me less enthusiastic about the orange hedgehog is that the yellow paint started flaking off immediately. I will have to scrub it all off because it looks terrible! The dogs don't care, but their owners sure do! I haven't had that problem with the sheep or the bears. The orange hedgehog is almost like it's from a completely different company!
