Booster Injection Question

Eemia

How long after can a dog get a reaction to the booster i.e. show signs of the possible disease they got injected with? And the older the dog is it more likely to show than a younger dog?

With pups or a dog that hasn't been vaccinated before the vet usually asks you to hang around for 10 minutes afterwards usually a bad reaction happens soon after. But some dogs perhaps have a milder reaction no idea how long from the time of the booster though best asking a vet.

Usually within the hour is when a bad reaction will happen (if it's doing to happen), but just keep an eye on them for 24 hours. Some dogs can be a bit under the weather for a day or two after their booster but most don't even notice it has been done! If it is a young pup you are getting done for the first time, you will need to keep them away from other dogs (apart from any dogs that live in the house) for a week to 10 days after their second jab to let them build up immunity. After this they can go for walks etc. but not before because they run the risk of picking up something.

With regards to age - very young pups and very old dogs are the most likely to have problems because their immune systems are not the best (but even at this, it is not common). Usually just feeling a bit off for a day or two is the extent of any reaction. If you are worried in any way, you can always ask your vet.
