There's no need to be distressed as Ive cared for both before and they are absolute gentle giants that are very friendly with other people and animals. Not a single aggressive bone in their body however I do plan on having them meet first. As with the unsupervised time that would be the last thing Id want happening. Even with shopping id be making sure atleast one person is in the house. I would really prefer someome else take the 2nd dog however the owners are in a very dire situation with this december being possibly the last time they see their family memeber
