Golden Retriever Puppy’s Bond With Baby Will Melt Your Heart

I’ve said it a million times before, and I’ll never stop repeating it: Kids who grow up with dogs usually turn out to be compassionate, responsible, and kind humans who care for others. Dogs are natural teachers of empathy and unconditional love, which honestly can’t be beat.

If you’ve been on the fence about adding a new pup to the family, Cosmo, the Golden Retriever, will convince you! When the 8-week-old puppy first arrived at his new home, Mom had her hands full with a 6-week-old baby girl. As difficult as it all felt at first, that turned out to be the best decision she ever made.

Cosmo was a sweet surprise who continues blessing us all with his vibrant personality. But it’s his bond with the new baby that’ll have you smiling the rest of the week. Take a look!

“Hardest six months of my life having a baby and a puppy that were the same age… but we couldn’t imagine life without Cosmo, and the way he loves on our girls made every hard day worth it,” the caption reads.

The video montage shared by @agoldendogmom isn’t only heartwarming, but also a glimpse of how joy-filled a life with dogs can be. It’s been two years since bringing home an 8-week-old Golden Retriever puppy, and the bond between Cosmo and the kids grows stronger every day.

The Story of How Cosmo Joined the Family

After losing Golden Retriever Jax, this family felt his absence in a big way. Though Mom was pregnant, it became clear that Loki needed a fur sibling to fill the void Jax left. Though she explained in an August 2025 video that it was the hardest, most exhausting time of her life, it was 100% worth it.

In the two years since Cosmo joined the crew, that 6-week-old baby girl has grown up with her very own best friend. Here’s your sign to get that dog!

Growing up with two earth angels like Cosmo and Loki means those are the luckiest girls in the world. One day, they’ll know it.
