Hello. Thanks for writing in. My name is***** and I would be happy to help you. I am not set up to do phone calls but would be happy to answer any questions you do have online. If you get a request for a phone call, it is from the website and not myself. I wouldn't be as concerned about the tear staining, unless there is something else obviously wrong with the eyes. Make sure the white parts are very red, there is nothing obstructing the pupil, there is no discoloration to the cornea, there is no squinting, there is no red mass in the inner corner of the eye and there is no thick or colored discharge from the eye. The tear staining is common with the breed and may show up a lot more if his fur under the eyes is white. As far as the poor haircoat goes, make sure he is not the runt and is getting enough to eat. I would also be concerned about intestinal parasites (i.e.; hookworms, roundworms, Coccidia, etc) or external parasites like fleas. All the parasites are usually easily treated, but if he seems smaller than the others or is more withdrawn, there may be other issues to be concerned about. Please let me know if you have any other questions or concerns. Hope this helps.
