Vaccinations Last At Least Three Years

ResearchBlogging.orgWhen reading Terrierman he made reference to the work Schultz has done on the duration of vaccines. Intrigued, I decided to read one of his articles. I dug up a review Shultz wrote on the duration of vaccines. It looks at available research on vaccines and their ‘duration of vaccinal immunity’ (i.e. how long they last).

Whether a dog has immunity can be determined either by antibody titres (a ‘titre test’) or a challenge study (e.g. deliberately exposing the dogs to the pathogen).


For distemper, parvovirus, and adenovirus the published data suggests an immunity period of 3 years or longer minimum.

Using blood products to test immunity, it seems that vaccines last 3 years or longer.  When using challenge studies, dogs that were vaccinated 11 years ago did not contract the virus.

According to this article, if a cat or dog is:

  • Vaccinated with core vaccines at 12 weeks of age or older,
  • Is revaccinated at 1 year old, and
  • Receives a vaccination “not more often than every 3 years”

then this would be as protective to the pet as annual vaccination.

However, non-core vaccinations last a year or less.

Table 1 shows estimated minimum duration of immunity for the 4 core canine vaccines.

How long does a dog vaccination last?

Shultz concludes, “Extending the revaccination intervals for canine and feline core vaccines does not place the animal at increased risk to developing vaccine preventable disease, but it does reduce the potential for adverse reactions”

He also recommends using titre tests to ensure that a puppy’s final vaccine enduces an immune response – and to revaccinate if the titre does not indicate that an immune response was produced.

Oh, and on cats? According to this paper, feline vaccines less researched, but feline parvovirus, calcivirus and herpes seems to last at least 7.5 years. Exception is feline leukemia which provides immunity for 1 year or less.

Nature’s Gift Natural Chews

I have always happily reviewed products on this blog, and as a long-time fan of Nature’s Gift, I was more than willing to review their new ‘Chews’ range when given the opportunity.

Nature's Gift Natural Chews

In our current climate, avoiding treats manufactured abroad is important – and so it’s reassuring to know that all Nature’s Gift products are produced in Victoria, from Australian products, and from human-grade meat products. Also, they don’t use palm oil in any of their products. So not only am I satisfied that this product is safe for my dogs, but that it is also relatively enviornmentally friendly, too.

Nature’s Gift generously sent us two packets of their new ‘Chews’ range: one of ‘Vitality Chews‘ and one of ‘Digestive Chews‘. (There is also a ‘Joint Chews‘ variety, but presumably they are more targeted at older dogs and they sent me products most relevant to my 6-years-and-younger household.)

Each packet contains 20 chews. Each chew is hard, crumbly, and love-heart shaped biscuit. They are easily broken in hard, but produce lots of crumbs! They are too large to use as training treats, and their crumbly nature doesn’t make them ideal for training treats anyway. They are pretty good at keeping a dog occupied mopping up all those crumbs though.

Nature’s Gift Digestive Chews

The novel thing about these treats is that they’re formulated to maximise the wellbeing of our pets. For example:

  • Vitality Chews target skin, coat and eyes, enriched with Omega 3
  • Digestive Chews target ‘inner function’, enriched with prebiotics
  • Joint Chews target joint health and function, with glucosamine (500mg per chew)

It’s an easy and (according to my dogs) tasty way to get some extra nutrients into your dogs, especially if you feel your dog needs a ‘leg up’ in some way. And, if you have trouble providing your dogs with these nutrients in conventional ways (e.g. have a hard time giving your dogs tablets or capsules) then this might be a handy solution.

Now, my dogs are not the best reviewers when it comes to the taste-testing – as in, they eat anything, and this was no exception. However, I was running a ‘full house’ at the time, and both foster dogs (Bandit and a beagle) and a litter of young puppies all happily sampled this product. (Despite the product not being ‘intended’ for puppies under 4 months. Oops.)

For those interested in ingredients, the Digestive Chews contain:

Rye Flour, Copra Flour, Fresh Australian Chicken Meat, Sucrose, Emulsifiers & Binders, DHA Omega 3, Prebiotics, Inulin Powder, Beet Pulp, Vitamins & Minerals, Natural Antioxidant & Flavour.

And the Vitality Chews have the following ingredients:

Rye Flour, Fish Meal, Flax Seed Flour, Soya Flour, Emulsifiers & Binders, Fresh Australian Chicken Meat, DHA Omega 3, Vitamins & Minerals, Natural Antioxidant & Flavour.

You will notice that neither of these chews contain red meat, which may be important for dogs with sensitivity.

The recommendations are for up to 4 chews a day, depending on the size of the dog. That means if you have a large dog, you might be looking at going through one packet every 5 days. If you have a little dog, under 5kgs, though, the recommendation is one chew a day. Because of the fortified nature of these chews, I would be inclined to stick to these recommendations.


These treats were certainly palatable, and I would  recommend that others ‘give them a go’ in situations where they think their dogs are lacking particular nutrients. While my dogs are fit and well, and weren’t given these on a regular basis, I cannot vouch for their effectiveness in helping the conditions that they claim too – but I certainly don’t think that they’d hurt!

I am likely to purchase the ‘Vitality Chews’ in the future following dogs being on a course of antibiotics.


Nature’s Gift Natural Chews are available in Woolworths and other supermarkets.

Product Review: Rose Hip Vital Canine

I have mentioned occasionally my first border terrier, MacDogald, and how he now lives with my parents. What I didn’t mention is that my elderly grandmother, who lives with my parents, somehow let Mac out of the yard. And when we found Mac again, he had a fractured pelvis.  His pelvis break went straight through the socket for his femur (his ‘hip joint’).  We knew Mac would never walk the same again, but after 6 weeks of crate rest, at least he was walking.

Our next step was reducing Mac’s pain as a result of the healed injury, as it was inevitable that he would develop arthritis in that joint.  He was started on a course Cartrophen almost immediately, and when he was due for the next course, his behaviour indicated that he was in pain as he was hesitant to engage in some activities. But even then Cartrophen was having a limited effect – as an 11 year old dog, it’s possible that arthritis was starting to creep into his other joints.

Container of Rose-Hip Vital.So, of course, when Rose-Hip Vital Canine contacted me for a product review, it was only fitting that Mac sample the product to see if it improved his comfort.

I must note that I’m very much a skeptic when it comes to herbal-whatsits, and come from a family of skeptics. Though I was reassured when I received a bunch of research papers with my trial sample, I was still skeptical.

But: We were amazed at Mac’s improvements on Rose-Hip Vital.

One of the most obvious signs of Mac’s pain was that he would hesitate to jump on the couch or the bed. Within a few days of the supplement, Mac had stopped planning his jumps and started easily hopping up.

A few days after this, Mac then stopped groaning when he moved in his bed or got up from laying down.  Presumably, the pain that was making him groan was now reduced.

Then, after about 10 days of first starting the supplement, he started running around the house, grabbing toys impulsively  and using the couch as his race track.

Not only did Mac’s pain-symptoms decrease after taking Rose-Hip Vital, but it did so dramatically over just 10 days.

Indeed, my skeptical-dad then went out and purchased Rose-Hip Vital (for people).  His results were less dramatic, but when he forgot to take his Rose-Hip Vital away with him on a weekend trip, he certainly regretted it!  It seems that perhaps Rose-Hip Vital built up more slowly for him and so the results were more subtle, but obviously cumulative.

Mac is not the only dog who has seen incredible results on Rose-Hip Vital Canine. My friend has a border collie with ongoing unresolved lameness issues which saw improvements with the product (see: Kenz’s Story – A Rose Hip Vital Success).  Indeed, the active Rose-Hip Vital Canine Facebook page has countless success stories of dogs doing better on the product.  A DogzOnline thread shows a number of people having success, too.

Mac continues to take Rose-Hip Vital Canine, and we have no plans of taking him off the product. I would very much recommend Rose-Hip Vital Canine for any dog with joint related issues. The results seen with Mac were significant and fast-acting.

Rose-Hip Vital Canine is responsible for dramatic improvements in Mac’s mobility and significantly improving his quality of life. We are so grateful for finding this product and finding the Mac we used to know again.

Mac going for a run!
