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.
Most good breeders don't let their puppies leave until around 8 weeks of age (and in toy breeds, 10 or 12 weeks), which means that your puppy may not have been leash trained prior to you picking him up. For large breeds, this may not be the case.
