Yes, my Pointer always has something in their mouth.

It's definitely not just yours. My Slovakian Wirehaired Pointer also loves to pick things up on walks. It's like a little game for him to find sticks, leaves, or even the occasional piece of trash! They are natural hunters, so I guess it makes sense that they want to carry something. Just keep an eye on what they pick up, as some things can be hazardous!
