3.5 months old, and he doesn't look tiny from your photos (but very cute!)
The breeder you got him from should have given him his first set of vaccines.
You got him his 2nd set when he had the reaction, and upcoming his 3rd?
What age did the breeder give him his first vaccines? If he was 8-9 weeks old, he may be protected. If he was younger, the odds go up that he may not be protected.
Puppy shots are only effective when given after the mother's maternal antibodies run out. Puppies are given three sets of shots, to be sure they develope immunity, and bc it is unknown as to when each puppy's maternal immunity runs out. It's different for each puppy in the litter. Two sets of vaccines is really all that is necessary to establish immunity, as long as the maternal antibodies are gone.
There are a few things you can do. You can ask your vet to run titers to check his blood for antibodies, which would prove (or not) that he has immunity. If the titer comes back 'low' it does not mean that he is not protected, but boosters may then be recommended. Titers are more expensive to run.
You could ask the vet to give him only half the amount of the vaccine. Knowing that the full amount is enough to protect a 100 pound dog, half the amount should be plenty for him.
Pre-medication is an option, but will limit the body's immune response to the vaccine.
You can make sure that the same brand of vaccine is not used. You'll have to get this info from the vet that gave the vaccines he reacted to.
You can request each vaccine to be given individually. They may have to order these from their supplier. Again, I would make sure they come from a different manufacturer.
As for the Rabies vaccine: Ask the vet at what age Japan requires puppies to be vaccinated against Rabies by law. Wait as long as legally possible, and never get the Rabies along with any other vaccine. It should always be given 3-4 weeks before or after a DHPP. In your pup's case, I'd opt for 4 weeks after, or the age Japan requires it, if it's later.
Puppies can have reactions for a number of reasons.
If vaccines are given too close together or in combination, it can overload their system, and cause a reaction. Your pup should have received his first set (from the breeder) @ Sept 7 (8 weeks), 2nd set @ Oct 5, (12 weeks) and 3rd set Nov 6 (16 weeks). If these dates are off, reevaluate his schedule. Also, sick pups should never be vaccinated while they're sick or running a fever.
They can react to the inactive ingredients found in the vaccine. Changing brands can help with this.
Many small breed dogs react to Lepto,and Corona vaccines, which are commonly combined with DHPP. I always read the labels on the vaccine container in the exam room to double check that these are not included, before the vet injects it. May look like DHLPPCv or DA2HLPPCv when included.
Hope this helps. |
