The dogs are cute but Canuck they will shed they are not Border Collies they are Malish or Mutts and could be the sweetest dogs as most mixed breeds are. They will need to be Wormed and get Vaccinated and do need heart worm medicine every month. Canuck with your allergies you really should get a dog that does not shed like a Poodle, Schnauzer,Airdale to name a few breeds. The thing is for those breeds they will cost you some $$ usually unless you let a vet know that you want to adopt one and maybe they can find one that is free or at least a good deal. There are thousands of Dogs (strays) in Cancun and there are spaying and neutering programs, Private organizations have campaigns and do the operations for free The Idea of Spaying or neutering is not very popular here yet due to cost but maybe the campaigns will help a little.
