Hi and welcome. Let me see if I can answer some of your questions. The price of females is higher because they are more in demand. Some people prefer females and some prefer males. The costs: It costs me $200 anually for their shots. Monthlly you have flea preventatives and Heartworm preventatives. I dont purchace either of these from the vet because I have found it cheaper elsewhere. I goot my advantage flea prevention on ebay for $18 for 3 months. I get my heartworm preventative Heartguard from Petshed. I forget how much it cost. Good luck |
