I hope the OP didn't dose her dogs with this. There are reasons why every company sells flea, tick, heartworm meds for different sizes. What is going on here is part of the big warning the USDA sent out earlier this year regarding medications. Do NOT try to dose your pets on your own.
You can get over the counter flea meds for today that will be the proper dose. Go to your vet to get a prescription on Monday. |
