Answer:
I have a soft coated wheaten terrier and he is about 5 years old. He is about like 60 pounds give or take. And i think that is an average size for them. Another soft coated wheaten lives next door to me and she is around 45 pounds. She is only 2 years old though. Hopes this helps
My Wheaten is 27 pounds and 2 ounces at her last wellness exam. She is a little small as most females are 30 - 35 lbs. Males are larger and usually go from 35-45 pounds but can be much larger.
Our breed has a STANDARD. A 60 pound male dog is either too fat or way over the height allowance set by that STANDARD.
