Intrude:

To put oneself in a place or situation where one is unwelcome or uninvited.

So Scooter has come to stay while my Mum is on holidays, i took this photo not long after Scooter arrived and it's a bit of a 'stand off' here between the 2 dogs.

Hagrid is really not impressed with Scooter staying here and patrols the edge of the couch so Scooter can't jump up on it. Hagrid definantly treats Scooter as an intruder! if we pat or play with Scooter, Hagrid gets so mad and will often ignore us unless we pay him some attention. Hagrid really is very posessive dog to own, but we love him anyway!
