Another way to make it healthier for your dog is to check titres when it's time to vaccinate. If titres of antibodies are still high, no need to inject dog unnecessarily. I'm going to go this way in the future. We just had 10 days ago rabies vaccination and Tank had a lot of unpleasant symptoms - slept for 2 days all day long like a rock, then became agitated, lost appetite for a week, ate half of his food and the rest I was hand feeding him, shed more than usual, eyes were runny. Hate this rabies vaccine! And some sources say dogs can have enough antibodies up to 7 years after vaccination, so im going to do titres in the future. In Europe everything operates on titres, nobody asks for rabies vaccination record, but they check your dog's antibodies titre.
