MIL has asked us to dog sit her dog for a weekend this summer. Her normal kennels are fully booked and sometimes DH's cousin will house/dog sit but isn't free that weekend. We have done it before but the difference now is that we have our own puppy who will be with us.
I tend to be more anxious about things and DH and his family are a little too relaxed (IMO). I'm worried about having the two dogs together all weekend.
Both dogs are crate trained and will sleep in crates in separate rooms. Both are girls and under 1.
Am I worrying about nothing? Any tips for helping them get along? (They have met once when our pup was very little and seemed to get on fine but haven't seen each other since as we don't live near them). TIA
