I didn't know a Great Pyr + hound could even occur due to the difference in size.
I neglected to put the complete breed description. We think the dad was Bloodhound. We know the Mom was full blood Great Pyrenees. Both of these dogs were on site and were 80-100 lbs.
I am pleased with the amount of productive effort I was able to maintain all through the day. I am 100% sure I would not be this active if I didn't have Grandkids with me all day.
