You should really look into Rimguard. It's food grade, biodegradable, non-corosive, non-toxic and tips the scales @ around 11 lbs. / gal. Anti-freeze would be around 8 lbs./gal calcium is 12 lbs./gal I had 28 gal. put in each rear tire on my B3300 Kubota. 616 lbs. and it cost me $151.00 installed. washer fluid (75 gal @ $2 each)would cost that much and anti-freeze will be more.(50/50 mix = 40 gal. @ $7+/ gal.=$280 ish) Then you have to spend a day putting it in yourself.
If the rimguard leaks out, it won't kill your dog. Just sayin.
