Your dog's dose of Meloxaid is individual to them, so you'll need to phone your vet and ask if you aren't sure of the dose. That said, the syringe that comes with Meloxaid has a scale in kilograms on the side of it - for most dogs, their weight on this syringe corresponds with their correct dose. For this reason, it's essential that you have a correct and up-to-date weight for your dog before giving them Meloxaid - your vet may have this recorded, but if your pet hasn't been seen recently they'll need to be weighed. Please double-check your vet's recommended dose before giving your dog Meloxaid, as vets may recommend changing the dose if your dog is overweight, underweight, or has concurrent health conditions.
