Trying to decide wether or not to adopt a Rescued Female Pyrenees

by Cheryl

My neighbor Foster's Pyrenees and for the first time he was given two puppies that were sadly found in a Dumpster. There were others pups but his two look "nothing" alike, however, from the same litter. He is planning on keeping the maie (which I originally wanted due to his calm temperment) and asked if I would like to adopt the Female which looks so much like a tru Pyr. Lots of hair which concerns me and her temperment is definitely like an Alfa Female.
Here are my concerns:
1) How will she adapt to a "very" anxious/skitzo (sp) cat that freaks over everything. We tried to adopt a stray male cat and my cat ended up with bald patches and hiding in odd places and also urined in my closet which he has never done prior. Will the dog attack the cat or disregard it all together?

2) We will be having a grandchild by year end so by the Spring time they would be sharing the yard - how will this Alpha Female take to the new baby after having this area to herself for so long?

3)I suffer from a chronic illness and will have days that I'm not able to walk her everyday - I have a large fenced backyard for her would that be suffecient excercise? Also, her Brother lives next door and could play with her.

I hope someone can put my head at ease because my heart is already struggling. She came in to this world in such an unpleasant manner that I want to do right by her AND my growing family.

Thank you.
