I posted here about ProMeris but I can't find it. Maybe it got deleted?
One woman with 7 dogs (larger dogs) used it and all 7 dogs got very ill and had to go to the vet. 3 had to stay overnight with IV's and stuff. The woman got sick too and was taken to the emergency room.
Her vet pulled it from his shelves and contacted the manufacturer.
I wouldn't touch it!!!
