The next step in training a rabbit to high 5 is to getting them to stand up. Even though this step seems completely unrelated to giving them a high five, you have to remember, most rabbits have really short arms and may not be able to balance themselves during a high five if they are on all fours.
This is why getting them to stand up can really help making the rabbit more comfortable while learning how to high five.
To make a rabbit stand on its feet, show them a treat and slowly raise it beyond their reach. If you do this slowly then you may see your rabbit standing up straight to get a hold of the treat you are offering.
Keep doing this for a couple of days to make sure that your rabbit is really comfortable while standing and happily taking treats out of your hands while standing up.
If you see that your rabbit is not standing or is losing their balance while standing then don’t worry. Some rabbits such as smaller breeds such as Dwarf rabbits or really large rabbits like Flemish giant rabbits can find it a bit difficult to stand up on their hind legs.
The next step will ensure that your rabbit can easily stand up and get into the movements of actually give a high five.
