Boomer joined the Thomas clan in November 2008. He was no bigger than a gerbil and twice as active. Without any training, he can pitch and fetch. And he sits up ALL THE TIME! Every day is a new day for Boomer and anything out of place requires immediate notification to family members.
This picture is the reason Boomer got his name. He played with this OU football that played "Boomer Sooner" when he shook it.
