Very few actions actually invalidate the Mass. And the Church says that as laity we should presume the Mass is valid. If later we discover it wasn't, no blame (sin) is assigned to us. That isn't something within our control.
Since this priest is the only one around, than you have no choice. Since, as you say, only six people were there, he may have been thinking it would be an experience similar to what Tim described. Since he didn't try to have you "co-consecrate", I chalk it up as weird, but not invalid.
The dog is just a strange thing though. What was the dog doing there in the first place? If it is the priest's dog, it may just have wanted to be closer to him. If one of the students brought it, that is just plan strange.
Perhaps you can try and organize a group to say Vespers together. Then you can continue even if there isn't a priest available.
The dog belonged to one of the congregation. Also, even though it was a mass at a campus center, I was the only student there. The other five people were elderly people who live in town. Since this is the only mass available nearby, they come to all the masses. On Sundays when we have the priest, this hasn't happened before, but there are usually about 15-20 people (students come on Sundays). It's near finals, so I supposes people didn't want to take off a half hour for tuesday mass (a rarity we only have during advent).
Also, thanks for the vespers suggestion. I don't know that I can get a group together, but I'm going to try.
