Colt's Birthday Cake

March 29 is our official date of birth for Colt. He is one and is still very energetic, adorable and still as naughty as ever.

Zack and I picked up Colt from the owners in front of a Petco. He was the last of his litter and we were told that he would be a German Shepherd. After watching him grow from a cute little teddy bear into this weird, cute little shaggy-haired dog, we knew he wasn’t full German. He had nice colorations, but he topped out at 50 pounds.

We drove him on his first cross-country trip to Wisconsin over Thanksgiving to see our parents. No one believed us that he was a German. For Christmas, my mom bought us a Mars Veterinary Wisdom Panel in order to test Colt’s DNA. It’s not super cheap, but it’s not over-priced either considering all the information you receive.

It turns out that Colt is 50% Australian Shepherd and only 25% German Shepherd. The test results dive into that his other 25% is a mixed breed that may contain terrier, guard, herding or sporting. It goes into detail about each group. So Zack and I did get a German, but only a little bit. His ears, coloring and excessive whining for sure.

Another good part of the test results is that we know Colt has the MDR1 gene. The MDR1 is a genetic mutation found in many of the herding breeds, some sight-hound breeds and many mixed breed dogs. These dogs require reduced drug doses for most drugs that are pumped by P-glycoprotein. It is good information for our vet to know.

  • Happy Birthday, Colt! I am sure he appreciated the effort you put into making him his special cake. What a fun treat for pups 🙂

  • I didn’t realize at first that the birthday cake was for your dog names Colt and not for a small child. Wasn’t until I got to reading your post that I realized I had it all wrong. What a fun and great thing to do for your fur baby to celebrate his birthday. Hope Colt enjoyed his cake.

  • I have never actually thought about celebrating my dog’s birthday, but I know she would enjoy a little cake like that. Your dog is adorable by the way.

  • This looks like a great cake to make for the dogs. I love Colt’s face. What a cutie! I have 2 German Shepherds that will be 9 this summer.

  • Oh my gosh, he’s so cute! Our dog has a ton of allergies so he’s not able to have many treats, but we’ll have to try an allergy-friendly version of this cake for his upcoming 8th bday because I’m sure he’d love it!

  • What a handsome looking dog! Happy birthday, Colt! My shih tzu turned 4 human years old last Valentine’s day and he still believes he is the alpha male in this household, hogging the couch, sleeping behind the main door (his protective stance), and giving a weird bark when a family member is sick. Dogs are family, that’s for sure. If only they could talk… Thanks for sharing the recipe. I’m making one for his next birthday too.

  • I would love to try one of those DNA tests for our dogs. One is supposed to be half German, but I don’t think she is.

  • This is so cute. I love seeing pets having fun birthday parties lol. Having DNA checked is a good thing. My sister would benefit from this! We don’t know what her dog is lol.

  • Aww, what an adorable pup! And how cute that you celebrated his birthday with a special homemade treat! Love this idea – happy birthday to your doggy!

  • What ever Colt is he is adorable. The genetic testing is something I have found to be interesting in both humans and animals. This dog cake I am going to have to make for my little man for his birthday in November when he will be 8 yrs old. Thanks for sharing the recipe and your cute little fur baby.

  • Lucky dog! Love seeing birthday parties for pups. Just too cute. I don’t have a dog to do that with and my cat could care less LOL! I’m not much on Pumpkin, but would see if I could do a different flavoring. Thanks for sharing!

  • Happy Birthday Colt!! This is so cute, my daughter always celebrate her dogs birthday and it appears he knows just when it is because she goes way out with surprises. LOL Now I need to share this doggie recipe with her for Royal!

  • Haha so cute! You treat your dog so well! I feel like a bad fur mother and will have to work on giving my doggie some delicious cake.. just for being such a good dog! Happy birthday Colt!

  • How cute! He looks very happy to be celebrating his birthday! I love that you made him a cake. I wonder if there is a birthday cake for cats? WE are not dog owners. just kitties! Happy birthday Colt!!

  • I absolutely love that you made a doggy birthday cake! I am going to save this recipe for mine! I am also a dog mom. I have 2 rescue dogs! One is a yorkie, we know for sure. Our other dog is a complete mystery, but we would like to find out what she is someday!

  • What a fun idea to make your dog a birthday cake. I’m certain that if this was a tradition that I started, that my kids would never let me not do it! He looks like he is having a great time for his 1st birthday!

  • We have never celebrated a pet’s birthday. Now, my sister-in-law would tell you a different story when it comes to her pets. I may just do this because my little chihuahua needs some special attention. Plus my four year old would enjoy making the cake.
