"We had new sod put in last November and were really disappointed when our redbone coonhound mix and our doxie terrier mix, urine was killing it sooner than we could even hope to plant seed to restore it. In the early spring we found this product. It helped put an end to the continued destruction of the lawn, as long as we remember to give them the pills very faithfully. They do not like the wafers, so I wrap them in a quarter of a slice of american cheese. This seems to have fixed the problem for me. They will eat the dog biscuits, but I am not convinced they work as well as the wafers. To sum up. Product works when taken as directed and you never forget a dose. The dogs will eat the biscuits easier than the wafers, but I think the wafers are more effective. If you have a picky dog, try the biscuits first. A 37.7 pound dog requires 3 of the wafers. If your dog is going to eat the cheese off the pill and spit the pill out, then this may not work for you and the biscuits might work better."
