In the criteria range for an Excel advanced filter, you can set the rules for the data that should remain visible after the filter is applied. You can use one criterion, or several. In this example, cells F1:F2 are the criteria range. The heading in F1 exactly matches a heading (D1) in the database.
Docking tails by banding is done when the pups are between 2-5 days of age, depending on the size of the puppies, and can be done in the box when the pups are suckling, or it can be done on a table with the pup placed on a towel.
There was no need as the tails were docked within 2 or 3 days of birth with very little pain or distress to the pups. Now, breeders have no idea what kind of a tail will develop. I hear that rottweilers are expected to have a labrador style tail - which will look very odd indeed. I suppose we'll get used to it.
