Update: I considered letting the dogs stay in the house last night, but after bringing them in, I wasn't so sure. Besides being wet and covered in sand, I have parakeets and a cat. I don't know if the dogs had ticks, fleas, or worms and really didn't want to expose my cat to that (she's 17 and has her own share of medical problems). Interestingly, my cat sat on the bed and didn't seem intimidated by them. But then I have babysat my friend's 130 lb bullmastiff and my cat has popped her in the nose more than once. I think the cat sensed they weren't bad dogs, just young dogs and she was ready to teach them a lesson. The lab kind of fixated on her, but it was more curiosity than prey driven. I was easily able to get her attention away from the cat so that was a good testament to her disposition.
I really didn't have a place inside to put them where I would feel they would stay out of trouble, as my house is not puppy proofed. These are young dogs so I wasn't sure what or how much they would chew up overnight, or what kind of trouble they would get into.
I have a screened in covered porch so I gave them a blanket, propped open the door, and they seemed happy enough. I heard them barking a few times last night, the last around 4:00 a.m. This morning when I got up they were gone, so I hope they went home. I left the porch open in case they come back and it starts raining. I'll pick up a bag and a few cans of dog food tonight in case they come back for dinner.
I am a huge dog lover too - I have had dogs probably 40 of my 49 years. But right now I am hardly ever home - gone between 10 and 14 hours a day -- and having dogs would be so unfair to them. If the owners don't want them, I'll be happy to take them until they can be rehomed. With the right owner these pups will be super dogs. They both have great dispositions and I think they will be good with cats, kids, and other dogs.
