So when do rabbits stop growing? Rabbits tend to stop growing and reach maturity at different stages and ages depending on their breed. Some of these rabbits, like the Netherland Dwarfs, attain adult size by at least 4-5 months old. Some other rabbit breeds, such as the Flemish Giants, may reach adult size in at least 18 months. Other rabbits like the medium-sized ones reach their adult size between 6 and 10 months.

Let’s take a look at a few of the most popular house rabbit breeds and what age each breed reaches adulthood. We will then proceed to evaluate the different factors that can affect how big a rabbit can grow and how rabbits live.

How Big Can Rabbits Get?

Factors that can affect the size of a rabbit include;

Breed

In as much as all domestic rabbits are of the same species, their breed can greatly alter their size while growing. For your information, dwarf rabbits are the smallest, they rarely grow bigger than 4Ibs but some larger species of this rabbit can exceed 20lbs.

Genetics

Even amongst the same breed of rabbits, some of these rabbits will likely grow bigger than others, strictly because of genetics. A mother rabbit with small body size and stature will most likely pass on this genetic trait to their young ones.

Care

The way you care for your rabbits can ultimately affect how big they can grow. Their growth can be stunted if they are not treated properly. As mentioned before, for rapid growth and development, young rabbits need to consume a considerable amount of alfalfa hay and pellets.

Be careful when feeding them with this hay because a little too much can lead to obesity in your rabbit’s.

It’s really not ideal to measure the size of a rabbit in inches, and also taking the measurements of your rabbits can be difficult, especially when they are running around the place. So its better and simpler to compare rabbits of the same breed based on weight.
