If your own fur baby is celebrating a birthday soon, here are some fun ideas.

How To Honor Your Fur Baby On Their Birthday

Celebrations, even small ones, are what makes this life meaningful and creating memories is just the best. And our fur babies deserve a celebration to honor all the fun, joy and love they give us throughout the year.

There are so many ways you can celebrate your pet's birthday. You can write a meaningful social media post like Seyfried did for Finny. You can have a total blowout party with all your friends and family, decorations, a dog friendly cake, a human cake, games and guests of all of the dogs that belong to your human guests.

You can do something as simple as taking your dog to the pet supply store and letting them pick out a new toy or treat. You can do a celebratory photo shoot with props like a birthday hat and balloons. You can go on an extra long walk, cuddle with them on the sofa, or simply tell them what they mean to you. A trip to the dog park, the beach, or a new hiking trail would probably make your pup's day extra special.

I think one of the most meaningful and kindest ways of celebrating your pet's birthday is making a donation to the shelter they came from of either money or some dedicated volunteer hours.

Our pets give us so much during their lives, so much love, companionship, laughter and joy. Celebrating them just makes sense.
