So big...so quick

The other day, I was out working in the lawn with Goose and our neighbor (who hadn't seen Goose in a couple of weeks) was amazed how big Goose had gotten in just two weeks. Because we see him every day, his huge growth spurts aren't as obvious to us (although I have noticed it takes me longer to brush him.) Here are some comparisons from the first day we brought him home until today.
Notice his tongue hanging out. This has been his "normal" look lately (mouth closed, tongue out). We're pretty sure his tongue has out grown his mouth at this point.
