I have a Boston Terrier also. He 9 yrs old and still acts like a puppy, most of the time. He is so good with the grandchildren, little Chloe even rides him. Oh did I mention his this the biggest B T the vet has ever seen. He weighs 38 lbs. and stands 16" from floor to top of back, but still wants to sit in my lap.
The second picture is priceless..Congrats you will have a ball with her.
