I am very sorry about your friends puppy.
Did he do any type of research before
plopping down $5,000.00?
I do not see any pedigrees listed on the website,
nor any health guarrantees etc. This to me
would be a red flag.
(since this is a business, I wonder if your friend can
contact the BBB and if his state has some type of law to protect the buyer like a lemon law?)
