My mother-in-law gives her 2 dogs heartguard but instead of buying the one thats for little dogs she buys the one thats for 50lb-100lb dogs and splits it into 3 sections and gives them that. Is that ok? Or can that give her problems, she doesnt care she just likes to do everything the cheap way. I told her thats not the right way to do it but she doesnt care. Does anyone have any advice or anything that I could possibly try and convince my mother-in-law not to buy that anymore...Thanks
I told her that was the wrong way to do it and she said " I have been doing it this way for 3 years" and I thought to myself just b/c you've been doing it this way doesnt mean it's the right way. I couldnt really argue back... Advice???
