Due to previously being a pet store manager, I would first say it is very typical for people to call a Shetland Sheepdog, a mini Collie.  I would first say never buy from a pet store since its a rip off and its never smart to not see the parents before making your choice.  I suggest checking out the classifieds of your local newspaper, free or not.  You could also do the craigslist thing which i have seen having given much success.  Good luck with your search and next thing to happen to you is having to choose between potential breeders. 

You might be more shocked if you knew what the legal definition of puppy mills is since it shocked me and its still hard for me to understand how so much awful places aren't puppy mills when its exactly what they are.  Actually, now I have to look this up since I never verified my sources information which all too often has me making a fool due to trusting everyone and anyone.  So not smart.  Off topic there, just establish there is nothing much for preventing or regulating puppy mills and pets stores all use the same few companies that sell dogs cheap and with that cheap price comes a huge profit and much abuse for the puppy and its parents and many new owners don't even know what they are even really getting.  Have witnessed some  crazy lawsuits stemming form pure breed dogs being tested and proven not so pure and people that did alot of research to establish the ease in creating a fake family tree which the store uses as notification of champions in its blood line which can dramatically increase the price since people are happy to pay more to show off proof of champion blood line but now I don't get to trust that stuff at all due to one couples research to reveal unjust actions which end up never changed anything and always take the quick and easy payoff money.  People truly rather take what they think is more money to let it go and keep quiet.  That so disappoints me but legal is just so much manipulation and so much games that I kinda understand.  Any way, here is a tidbit of fact straight from Wikipedia.org;  Common problems

Due to the frequently poor breeding conditions in puppy mills, puppies bred there often suffer from health and/or social problems. Puppies raised in a cramped environment shared by many other dogs become poorly socialized to other dogs and to humans. Dogs are then transported over long distances in poor conditions, sometimes resulting in animal stress and death. As the surviving mill dogs grow older, they are more prone to developing respiratory ailments and pneumonia, as well as hereditary defects such as hip dysplasia.[2] In addition, mill dogs are more prone to have problems with their temperament. Puppies from mills are usually sold as purebred dogs in an attempt to attract the higher prices associated with purebreds. However, due to the indiscriminate breeding practices of puppy mills, the dog may not actually be a purebred puppy.[14] The vast majority of puppy mill animals are sold to pet stores by "dealers". Some puppies are sold by dealers masquerading as authentic breeders.

Talk about a tough job choice since to help the dogs, comes much lying, deceiving and pretending when it comes to authority types.  I hate lying but my heart couldn't stand knowing a pet store was poorly managed and had frequent deaths which just as promised along with other funny promises given to the best district manager I've ever met to get the job.  Just as the company used and abused her, which one can only handle for so long since it can be costly to a manager and district manager to due for the dogs what the company cares less about.  The crazy other problems I quickly turned around and changed was no more dogs dying ever which is something don't care about but don't want to hear about, eliminate a awful spell that spread to many stores surrounding which Is hard to believe I got no props from my company but only that of mall management and then there was a mouse problem which a paid for and well known extermination company which must have been paid bare minimal due to nothing they did eliminated the problem but then I added in ways I learned from research to quickly and easy rid the store of all pests and eliminating the need for a ban on selling mice since it was falsely though it was loose pet store mice when they were all so wild and simple came it holes to outside and stayed since the store wasn't made and kept clean until me.   wow, i could go on and on about pet stores but i'll quit rambling and stick to answering questions that I feel my experience add an outlook for many pet questions.  

Now let me add by restating that I loved the comment and you are all so right which is sad but true.  The sad thing is that people wont stop buying from pet stores until regulation prevents a large portion of puppy mills by forcing guidelines.  Someone in some office needs to speak for all the puppies dying and going through awful torture which is so known that it makes me sick that it still goes on. 

More from wikipedia.org that cracks me up and reminds me that the people paid to protect the animals must be paid off or are just not given any power or time to regulate since I saw countless illegal acts being obvious but I guess people have to go straight overboard with complaining to create some little monetary amount that isn't significant enough to be a deterant.  

The Animal Welfare Act (Laboratory Animal Welfare Act of 1966, P.L. 89-544) was signed into law by President Lyndon B. Johnson on August 24, 1966.^[1] It is the only Federal law in theUnited States that regulates the treatment of animals in research and exhibition. Other laws, policies, and guidelines may include additional species coverage or specifications for animal care and use, but all refer to the Animal Welfare Act (otherwise known as the "AWA") as the minimally acceptable standard for animal treatment and care. The USDA and APHIS oversee the AWA and the House and Senate Agriculture Committees have primary legislative jurisdiction over the Act. Animals covered under this Act include any live or dead cat, dog, hamster, rabbit, nonhumanprimate, guinea pig, and any other warm-blooded animal determined by the Secretary of Agriculture for research, pet use or exhibition.^[2] Excluded from the Act are birds, rats of the genus Rattus (laboratory rats), mice of the genus Mus (laboratory mice),farm animals, as well as all cold-blooded animals.^[3]

As enacted in 1966, the AWA required all animal dealers to be registered and licensed as well as liable to monitoring by Federal regulators and suspension of their license if they violate any provisions of the Animal Welfare Act and imprisonment of up to a year accompanied by a fine of id="mce_marker",000.^[1] All facilities covered by the Animal Welfare Act were required to establish a specialized committee that included at least one person trained as a veterinarian and one not affiliated with the facility. Such committees were to regularly assess animal care, treatment, and practices during research, and were required to inspect all animal study areas at least twice a year. The committees were also required to ensure that alternatives to animal use in experimentation would be used whenever possible.

Although hygienic living conditions were necessary for animals not during experimentation to prevent unintentional infection, there were no such provisions against intentionally infecting animal subjects with disease for the purpose of the experiment.

Now i'm so shutting up and apologizing due to my obvious problem with what pet stores and the pet stores I managed and all this venting which is so overkill since I doubt this will get even one person not to buy from a pet store.  No one can resist if they dare enter one.
