Trailer is a 12 week old, male puppy. He is... hmm... maybe... Cairn Terrier Mix? We have no clue. Your guess is as good as ours!! He only weighs about 5 lbs and the cutest, shaggiest, softest pup ever! We LOVE him. He loves every dog he meets and is great with kids. Please email leslieoakley@sbcglobal.net for more information.
