LEGO Pets! Building Instructions for Dogs, Cats, Guinea Pigs, Lizards, and More!

At our house, we love LEGO® and we love pets! We currently own a dog, two guinea pigs, and a bearded dragon. So it’s no surprise that we have several LEGO® pet projects to share with you!

Updated 8/31/18 with new projects added!

Build four different dog breeds, some adorable cats, guinea pigs, a lizard, and a goldfish!

Dogs:

Building instructions for our LEGO® dogs are in four posts: LEGO Dachshund and Mastiff and LEGO Beagle and Westie-type Dog. (Note that the dachshund has complete instructions, but the mastiff does not. I had sick kids that week. It does have photos from multiple angles!)

You can also find instructions for building a LEGO terrier dog here.

And then there are instructions for building LEGO puppies here.

Cats:

You can find building instructions for the cats here: LEGO Cats

These little kittens have an adorable amount of personality. I didn’t want to take these down once we made them! But eventually we needed the parts for other things… sniff…

Guinea Pigs:

Build some guinea pigs with a cage and a water bottle! You can find instructions for the guinea pigs here: LEGO Guinea Pigs Building Instructions.

Lizard:

Gresham (age 9) designed this little lizard, and I love it!

See how to build the lizard here: LEGO Lizard Building Instructions

Goldfish:

We didn’t have enough clear bricks or windows to make a fish tank, so Aidan decided to use a few clear bricks under the fish to make him to look like he’s swimming.

Step 1: Find a 2 x 3 brick and two 2 x 2 inverted slope bricks.

Step 2: Add a 2 x 4 plate, two 1 x 2 plates, and a 2 x 2 plate (photo shows two more 1 x 2 plates).

Step 3: Add two 1 x 1 bricks with a stud on the side and eyes. We used yellow but orange would be even better. Add a 1 x 2 – 2 x 2 bracket and a 2 x 3 brick.

Step 4: Attach a 2 x 2 slope to the bracket on the front of the fish. Add a 1 x 2 brick and a 2 x 3 slope. The find the three bricks shown below the fish.

Step 5: Build the tail with a 2 x 3 plate, a 2 x 2 brick, and a 2 x 2 slope brick.

Step 6: Add a 2 x 3 wedge plate on each side for the fins. Built the top fin with a 2 x 3 plate, a 1 x 2 plate, and two 1 x 3 curved slope bricks. Behind that add a 1 x 2 brick and a 1 x 2 plate with one stud on top.
