Hi there SWAG - I can see how HEMI got her name / nice, happy dog.
My dobe Amy, also likes to go for rides - she will pout, if I leave her behind...
Since your in Ontario to, please feel free to check out my "pet" related web site. www.petperfectexpress.com
(I helped a Mastive overcome hip problems, some 8 years ago, and now she's a healthy 200# female)
Mastiffs are also known as the gentle giant and are very laid back and confident in there abilitys. They will however protect the family if the need arises. :Stop: Hemi comes in at a trim 250 lbs.:thThumbsU
