"Slight used.... but in good condition" 

Rescuing an animal is not always as sentimental & romantic as it sounds, nor is it always an easy assimilation into your family.
Expecting a creature to be grateful to you (as the savior) & immediately come  around in attitude/health is just plain foolish thinking.
Animals do not know much more than what was genetically encoded, enforced by positive/negative experiences from birth.  Genetics & history blended w/ temperament creates the cute/pitiful/willful/barking/cowering/cuddly creature that stands before you today.
Post-rescue, an animal peels in layers like an onion --- physically, mentally & emotionally - today & tomorrow may present two very different animals.  
*A 1,000 lb. horse that swings his head each time you lift your arm could easily dole out a concussion to the human handler.  
*A dog who has fought for scraps usually does not readily find a smooth path into their new pack without continuing to fight at each meal. If submissive, they may grab a morsel, retreat to an area (under the bed) and not come out for food or water - for days.  
Some have lost their homes due to divorce/foreclosure/illness - they are nervous & needy w/ raw emotions, pining for their pack.......holding onto the anxiety they absorbed from the owners prior to  move - &  the pain of being left behind.  Often times, they take 2 steps forward & 6 steps back.........
These words should not change your heart or yearning to rescue - only clarify the situation.  
For many years, Bellissima Farms has worked to rescue animals from a variety of unpleasant conditions, including breeding facilities.
With BFII ranch-bred animals, everything is known from genetics, prenatal care, groceries, vitamins, exercise, health history, worming, innoculations, temperament, reaction to stress, known allergies, dominance/submissiveness, etc. 
Rescued animals have an equally interesting background, but their secrets are partially revealed -- in slow chapters of discovery -- if ever at all. 
On the positive side, sometimes -- all that’s needed is a good balanced reliable diet, a couple of wormings, lots of baths & brushing, fresh hair cuts, dental scaling/teeth floating, nails trimmed - and lots & lots & lots of hugs & scratches. Sadly, in other instances, vet fees & meds are an unending spiral of bad news --nickel & diming you to death, ending unhappily in unavoidable euthanasia. 
Ask yourself if you can invest - financially or emotionally.
Change does not happen overnight - patience & understanding is mandatory.  
But - most times, patience & understanding delivers scrumptious, substantial, life-changing rewards.
For the rescuer, the health history is a mystery so the entire inoculation/worming schedule should be repeated.  Days of shaving & grooming may be necessary to relieve a matted coat, heal/medicate skin irritations, clip elongated nails.  Ears may have a build up of debris, errant, ingrown hairs & possibly ear mites.  Introduction to a regular grooming routine can be emotional - taking one person to hold/calm the animal while another completes the labor.  The introduction of grooming should evolve from an invasive, noisy, frightening situation to something pleasant & anticipated -- perhaps a "spa day"...............
If there are already dogs in your household, weigh the new animals ability to feel comfortable w/ the old timers --- & vice versa.  Be certain you are permitted to have a "trial run" w/ the new personality - & are able to return the pup if clashes occur.
Many rescued Cresteds have been bred - & without fail - have notable deformities that should NOT be repeated - therefore, adopted pups should be rapidly neutered/spayed & have dental work while under anesthesia.  BFII completes as much as possible, however, at times, we are unable to keep completely current due to volume of rescues or quick adoptions.
Not every human male/female makes good parents - not every animal w/ "breeding equipment" should be used to pro-create. Active hormones are demands made by Mother Nature - don't expect your dog to disobey her call, regardless of training.  
In addition to unpleasant hormonal behavior, removal of reproductive organs in both male/female stabilize the personality, increase the learning curve/attention span & reduce the chance for cancer.  Spay & neuter is a good thing!  
When looking to rescue an animal, it is imperative one possess the time, patience (& wallet) - to overlook bad behavior while enforcing new house rules.  Some animals require thousands & thousands of hugs before they respond, while some never respond the way in which you wish they would.
Some will never trust.  Ever.
A rescued dog is not free - as "free" could translate to "without worth".  A rescued pup has already experienced a history of bad luck -- it doesnt need any more.  A monetary, albeit small, value is assessed to each pup, partially to recoup expenses & partially to guarantee the dog is not going back into another crummy situation.  People who cannot afford the rescue fee usually cannot afford balanced dog groceries, vet care & other necessities.  It sounds harsh - but is not intended to be.  Whats the use of being rescued if conditions are not improved? 
Papers are not available on rescued pups - they should be vet checked & "fixed" ASAP.  Also, regardless of beauty, due to questionable genetics, rescued pups should never be bred.  If you are crazy about them - just rescue another - there are dozens waiting for homes.
Please consider opening your heart & home to a crested who needs you - it  may be the beginning chapter in The Story of Your Lifetime .

The one thing I can promise you, your life will never, ever be the same................
