Product Overview
Adjust your soil with Mag-I-Cal®! Jonathan Green Mag-I-Cal® for Lawns in Acidic Soil helps rapidly raise soil pH that's too low and stimulates healthy microbes in the soil. Healthy, lush lawns thrive in soils with slightly acidic to neutral pH levels ranging from 6.2 to 7.0. When soil pH levels drop between 4.0 to 6.0, this creates an environment for weeds to thrive and grows a lawn full of light green unsightly grass.
Mag-I-Cal® for Lawns in Acidic Soil contains pelletized calcium carbonate, or lime, in a completely soluble form that is immediately available to rapidly and efficiently raise soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. Where it may take several bags of lime to balance low soil pH, Mag-I-Cal® for Lawns in Acidic has the power to do it all in just one easy application!
Additionally, Mag-I-Cal® for Lawns in Acidic contains humates to stimulate beneficial microbes in the soil.

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.
