The problem with Capstar is that it only kills the fleas that are immediately on her...it doesn't keep them away, so you'd have to literally give her capstar all the time. I think I paid $8.00 for one capstar pill at the vets, so it would get pricey.
I don't know if you can give Frontline to a pregnant dog, but something that kills both the biting fleas and the eggs would be best...of course, only if it is safe to give a dog that's prego.
BUT...even then...they puppies would still be in danger. Puppies can easily become anemic from biting fleas....and I am guessing that's what would happen to them if they were born under the porch...not to mention the fact that it is HOT HOT HOT in Florida.
A bath is going to do less than the capstar would. I've given my dogs a bath in dawn dish soap and still found fleas running around...and as soon as the dog goes back under the porch, she will be covered with them again anyways. They could always bomb under the porch and spray their yard with something like 7 dust(assuming it's safe for a pregnant dog to use the yard afterwards) but what are the chances of these people going to all that trouble when they don't even take care of the dog in the first place.
I would simply ask them if I could have the dog. Heck, you could offer them $20.00 to buy the dog from them. Or...you could get the SPCA involved and I am guessing they'd probably remove the dog OR at least make sure the people get proper vet care.
I totally know what you are going through...as far as not wanting to rock the boat. I have a neighbor who literally uses the house next door as a dog kennel. He comes over no more than ONCE a day for about 10 minutes to feed and let the dogs outside...and you know dogs potty more than once a day. They are getting food and water and are healthy weights...but still, they are lacking human interaction. On top of that, there is no AC in the house and I can't see ONE window open!! Can you imagine how hot and stinky it is in there?!? They have a fenced in yard...how hard would it be to put in a doggy door...or even easier yet...open a few windows, at least on the second floor!!
Still...I don't want to start world war 3 with my neighbors, because they are moving in this fall....On top of that, I know Animal Control won't do squat...because they do have food, water and shelter. They've already been called by the neighbor down the street and they wouldn't even bother to come out. I don't know what the difference is btwn leaving a dog in a hot car with no windows cracked and a hot house with no windows cracked...but I guess that's ok
