All shelter animals are vaccinated with 5 to 10 vaccines on the day they arrive. If they've already had just 1 vaccine prior to this, they are now over-vaccinated. Combination vaccines are terribly damaging; the immune system is over-loaded instead of being able to deal with 1 disease/vaccine at a time as it would in nature. This is why all good vets like homeopaths recommend only 1 vaccine at a time and at least 4 weeks between each for people who choose to vaccinate.
Our family owned several rescue dogs in the past; all of them had serious health and behavior problems. It usually showed up within days or weeks after they'd been vaccinated by the shelter. Allergies, seizures, aggression. I realize money is an issue for shelters but rescues should run a titer test and save the poor animals from a lifetime of suffering and bad health....safe the owners a lot of heartache, too. Hemopet in CA runs titers for very little and the blood can be sent by mail. I think the last rabies titer we ran was only $80. Distemper and parvo are another test and it was about $40-$45.
All that damage is why my hubby said never again to a shelter or rescued pet. Our next pack will be strictly from a natural rearing breeder.
