<p>Sorry you are in this. It is not the dog’s fault nor your fault.</p>
<p>I started a purebreed rescue about 12 years ago that is still going strong. Not all placements work out.</p>
<p>I will tell you that rescue is not an easy thing, however there are a ton of outfits that call themselves rescues that are not. I can’t say whether who you dealt with was legit or not, but sometimes we would <em>list</em> dogs for other <em>rescuers</em> and in that case we made it clear we had not met the dog.</p>
<p>If this dog has huge paws it could well still be a pup. A pup has all its adult teeth in at 5 months. They are mostly in at 4. And if it is a large breed dog, 9 months is still pretty young.</p>
<p>And as far as figuring out what mix dogs are - well it always anyone’s best guess. There is no way to know unless you actually have seen the sire and dam.</p>
<p>I am sorry about your cat, I hope he survived, but dogs have prey drive, some higher drive than others, and again there is no way to predict that. Some breeds are predisposed to higher prey drive and some are predisposed to little prey drive but there are always exceptions to the rule and you will never be able to tell until they are in a situation where a small animal flees and you see how the dog reacts.</p>
<p>Someone suggested getting the dog healthy and working on rehoming. I agree with this. She sounds like a great dog for the right people and should be in a home without other small animals (the cat incident has NO bearing on how she will be with children - but I would monitor her in some situations around children so you can make a good placement). In the meantime, keep the cats in a separate area for their safety.</p>
<p>I would also get her spayed before placement. The last thing you want to do is be responsible for more puppies. It is safe to spay large breed dogs quite early and before their first estrus is usually best for their long term health</p>
<p>Your most difficult task is going to be getting rid of the fleas since you have more than one animal and the eggs are now in the house. </p>
<p>And despite the fact that this pup is older than you thought, it is still a puppy and being in a crate all day guarantees hyper behavior when she finally gets out - so some of that must be expected. </p>
<p>Make her the best and healthiest dog you can so she can be placed in a good home. </p>
<p>Good Luck</p>
