You may have some species or breeds that you would like to remove from Evetpractice. Here are the steps to do so.
You can relocate one species into another to consolidate the list.
You can go to Settings gear icon > Classifications and click on the link "Delete/Relocate Species"
On the Relocate Species screen you would select the one on the left that you want to relocate (for example Unknown) and then select the "To Species" where you would then select the species you want those moved to ( such as other)
You will also want to select the option "Delete species after relocation" before you click on the "Process" button.
