I have a Westie named Rascal and he is just fantastic!!! I actually got my Yorkie (Sassy) so he would have a playmate.They are wonderful together but I must stress a lot of hard training work involved with a westie as well as a yorkie. They can be quite destructive when they are young but if you have the time and training required for them then they are great! I hate when people pin bad reputations to a breed because usually the ones who have probs with them havent properly trained them. They are full of energy so a good match with a yorkie but require more excersize. You absolutely MUST walk them at least once a day . I can't walk very well so usually I alternate between walking him and taking him with me on bike rides. He prefers the bike rides because then he can go faster which he loves! I also put him thru obedience training and he was at the top of the class all the way thru ! He actually missed it when he graduated and couldnt go anymore!
They are very sensitive to certain foods and do tend to have allergy issues so if you dont have a deep pocket then dont get one. It took me 3 years and allergy testing and having serum developed according to his numerous allergies. He is doing great now! I feed him only grain-free food (he is allergic to grains) and they usually dont digest beef well so I avoid that like the plaque! I am rambling so I will close and I believe if you can handle a yorkie then you can handle a westie! They are both high maintenence! So be sure you can handle 2 high maintenence dogs and ENJOY!!!
