I did a search here and on the web in general, but couldn't really find much information. I know that some illnesses (parvo, distemper?) can be passed indirectly from an infected dog to an unvaccinated puppy. Can puppies contract disease from indirect contact with other animals? We have a number of deer who hang out in our yard; could they transmit anything to our puppy? I know to look for ticks, but is there anything else we should be aware of?
