nuzzle

For a veteran with PTSD, a service dog may retrieve medication or perform anxiety-relieving actions like nuzzling or leaning against a person when the dog senses a heightened state of anxiety.

"FYI we did NOT feed them as that is not allowed - they came up and nuzzled us so we just gave them a little pat then let them be."

Picture the soft, cool nuzzle of your dog.

A small grey kitten with an injured nose kept jumping on his shoulder, nuzzling him.

As soon as the two goats were introduced, Harold showed lots of interest and went over to nuzzle them.
