dogs have no real concept of time. … Although dogs may not know exactly what or when their birthdays are, they can definitely tell how long it's been without something once they're reminded of it.

We don't know what they know, because they can't tell us; we only know what they do. We can see that their behavior changes when the environment changes. Things like special food, a tree in the house or other decorations will cause them to investigate.

We don't know because they can't tell us... and vidushi is right.

Yes Vidhushi is right Even though we know their birthday Thay can't tell us whether they know it

So it's always going to be a surprising birthday party for them. Good to know that 🎉🐶

Yes Vani 🤗
