Time flies — in the blink of an eye, your little adorable pet turns into a strong and sometimes sly animal. Needless to say, that friendship that develops from childhood to adulthood often grows into an even bigger friendship. And the characters of our compilation are well aware of what growing old together is like.

We at Bright Side were amazed at how strong the connection between animals can be and are eager to share some examples with you.

Love is about growing old together…

,

…keeping old habits.

,

…and hugging the same toy.

,

… and growing strong.

It’s when you stay the same little puppy inside…

,

Sometimes one of you might grow more…

,

Bonus: Growing up with owners can be fun too.
