how to build pups immunity

[runningbeat]

My pup first had giardia when I brought him home at 9 weeks. He was treated 2 times with different medications. He also had amemia, found this out by blood work and stool samples.
Now he just turned 4 months and has giardia again.
Yes, I clean up after him everytime, bath him often and spray area with bleach.
Vet told me that some pups don't have a good immunity and that's why they can't fight it, and other pups can.

So my question is, what product can I give him to build his immunity.
Also how long does it take pups to build there immunity,

I'm currently researching colostrum for my allergy dog. You might want to google up on that for your pup. I think that basically though, you just get pup as healthy as you can and the immune system takes care of itself. Ask your Vet about colostrum. I had no idea it was even available as a supplement till a few days ago.

I'm not sure if you are a RAW feeder or not or what food you are feeding but diet would be one of the first things I'd explore. High quality food should be on the menu imo, but others know way more on the topic than i do so I'll let them chime in.

pup is on summit puppy, but....he was tested positive for giardia 3 times, been on medication 3 times, vet says he has trouble fighting it because his immunity is low.

Some vets use flagyl to treat giardia, while others have found that panacur is much more effective. What have you been given for treatment, and for how long?

Probiotics away from any antibiotics are a must. I have read that MSM has some activity against giardia, but have no experience with it.
