It's likely a prairie dog.
That is good. Meets the criteria of blunt nose and the ears are not prominent.
There is the matter of the front legs. Seems I can see a shadow under the entire prairie dog. The only thing I can see that looks like a leg seems very, very short compared to the pictures I just looked at. It also seems more like being part of the cheek than a leg.
So if a prairie dog which live in these areas:
The location of where the photo could have been taken can be narrowed down.
I tried to rule out any of the species but could not since they all appear to have the same coloring among them and nose shapes.
If the photo was taken outside and not on a set I think it might have been taken in an arid area.
So looking at prairie dog ranges and arid areas with low vegetation maps it looks like maybe West Texas, New Mexico or Arizona.
Here is Texas:
Here is New Mexico:
Here is Arizona:
By the way I did this, because I got tired of seeing answer from FE's just basically saying because that is how it is. I actually researched and came up with locations that if it is a prairie dog where the picture could have been taken. I did not just say it looks like a rodent and 10 out of 10 people thought it was.
At least for me and I am sure others this is the kind of stuff we are talking about when we say evidence. It showed locations where prairie dogs live, places that and/or had limited vegetation, and pictures of those states that both prairie dogs lived and somewhat matched what we can see in the photo. I did not research any further to see if prairie dogs live in the areas the photos I posted.
I also assumed a prairie dog did not end up on an indoor set.
I still think it is a picture of a rock that looks like a prairie dog with no front legs.
