While we have had some recent growing pains in the distribution of our products, we
continue to believe in providing the highest quality whole food nutrition to dogs and cats. With this in mind, after listening to clinics and pet owners and working with a variety of experts, we are making some changes to our wet diets.  As part of our commitment to integrity and transparency, we are providing this update on the following changes:

•The Canine Growth/Sensitive GI wet diet has a different protein source:

• Now contains turkey rather than pork, the same protein source as the dry diet.

•Adjustments have been made to diets to meet the AAFCO 2018 nutrient requirement recommendations.

• Marine microalgae, a unique vegetable source of EPA/DHA, is being used instead of
fish oil in Rayne diets, with the following benefits:

• Reduces the chance of protein contamination for very sensitive food allergic pets. 

• In the Healthy Reduction-MCS dry diet, the EPA/DHA levels have increased without altering fat content or caloric density

• Feline wet food containers – an exciting change!

• Will now be in cans instead of the foil-topped tins, which should help to eliminate  issues with broken seals from transport.

• All canned foods will be now be produced by a trusted facility in the United States, which has already been producing
some of our novel protein diets.

• Changes in can sizes:

• Canine wet diets – new cans will be 369g vs current cans at 400g   

• Feline wet diets – new cans will be 156g cans vs the current trays at 100g  

• We will be adjusting the feeding amounts/guidelines accordingly

• Changes in appearance, texture or consistency of wet diets made in North America
may be seen when compared to the previous diets made in Australia:

• The new manufacturing facility may use different temperatures at mixing and filling  
than the previous facility, which are the main reasons for changes in texture or colour
and also for the improvement in consistency.

Note: some pets may initially reject the new diet because of the differences and owners may have questions about the difference in appearance. Please consider reaching out to your clients who are feeding their pets Rayne wet diets to let them know that when they are ordering new food, they should allow for the proper transition time to the new diet. 

If you have any questions or need further assistance, please contact your Rayne representative or contact customer service at or at 855-850-1410.

Greeting Rayne Prescribers,

We’re writing to you to update you on Rayne Clinical Nutrition Product Availability. 

Our distributor, Pacific Veterinary Services (PVS) made a sudden decision to not replenish their inventory from Rayne and as a result there has been a spike in back ordered items from PVS.  In order to fix Rayne’s out of stock and service problems from PVS, we’ve been working diligently to rectify any PVS back ordered items to the Buying Groups. We apologize for any confusion, the coordination for inventory management between PVS and Rayne has not been well communicated. 

The Buying groups are still rightly ordering from PVS and then for the PVS back-ordered items the buying groups are ordering directly from Rayne. We have been balancing our inventory production to accommodate the inventory levels currently still available to be purchased from PVS. Inventory will be arriving at our warehouse on a regular basis to ensure our full product line is always available. 

The back-orders from PVS may have been misunderstood to mean they are also out of stock for Rayne Canada in general. Apart from a few items currently in production, this is false information. Hospitals can order from their Buying Group as per usual, and Rayne will fulfill Buying Group orders for items that PVS does not have available.  

Rayne has stock in our warehouse and Rayne’s production facilities, have no manufacturing issues and indeed Rayne has plentiful supply of product to service the growth of our product. We expect the co-ordination issues to be resolved shortly.

A few items are temporarily not available through PVS or Rayne; here is the status and ETA on these 4 items. (Please note these items represent less than 3% of our overall sales volume)

1. Healthy Reduction-MCS 3kg – We have a shipment arriving at our
warehouse on November 27 and again on December, 3. Note large
bags are currently in plentiful supply. 

2. Rayne Feline Rabbit 3kg –Product will be available at the Rayne
Canada warehouse on December 15th. Note: We shipped available stock
direct to some buying groups from our Rayne USA inventories, so some
bags can be sourced. 

3.  Sensitive GI Revive Feline/Canine 400g - Product will be available in
  the Rayne Canada warehouse by mid- January 2019.  

4. Crocodilia wet canned food, Alligator Treats and Canine Crocodilia
Maintenance Dry- As has been previously communicated, we are
working through a border documentation issue related to new USA
export regulations. Crocodilia will be available at the Rayne Canada
warehouse by February 2019.  Our nutrition team has recommended
alternative diets that are also available. 

Again, we apologize for any confusion that the PVS communication of out of stock has created. Rayne has sufficient inventory and we are shipping to the Buying Groups on a weekly basis.  Our Rayne team is dedicated to the health and welfare of all the pets currently on Rayne diets, and we understand how important it is for product to be available. If you have any questions or we can be of service, please contact us.  

We appreciate your business,

The primary philosophy of Rayne Clinical Nutrition is to bring simple, natural, whole food products to the veterinary market. Working with whole food ingredients is more challenging, but we are determined NOT to compromise our philosophy.

WHAT DOES THIS HAVE TO DO WITH YOUR BEST BUD’S JERKY? of the things that makes our jerky treats so healthy and versatile – and useful even with dogs and cats with severe allergies – is that they are VERY simple ingredient. Every jerky has the same ingredients, 99% meat and 1% molasses and sea salt (and two natural preservatives). The molasses give the jerky a great texture and mean you can tear the treats into tiny pieces appropriate for kitties or for training, etc. The sea salt is part of the preservation process to ensure a safe, long lasting treat WITHOUT using any chemicals.

Very often you will see ingredients like ‘propylene glycol’ in pet treats (and human food!). This chemical emulsifier helps preserve the treat and will keep salt from leeching out and becoming visible. Although this is safe and effective, it does not meet with our philosophy of natural, simple, healthy products.

There are times that you will see visible “salt leeching” in your Rayne jerky treats, it will appear as a white residue on the surface of the treat. This can be after the treat has gone through different temperatures (for example while in transit to your veterinary practice) or can just happen over time. This absolutely DOES NOT represent any health risk to your dog or your cat. Every single batch of jerky goes through extensive testing before it is released into the market. We know that every piece of every batch is safe, tested, healthy, and delicious!

We take the responsibility of being part of the medical management of patients in veterinary practices across Canada very seriously. We make these treats with the highest attention to quality and safety for your pets, and for ours. We feed these treats to our pets, every day. After all, we are pet owners, too.

If you ever have any concerns or questions – reach out to us at
We want to hear from you and hear about your pets!

Great news! As you likely remember, back in April 2017, our Canine Low Fat Kangaroo-Maint Wet was slightly out of the range of our typical key paramaters. That production run was a bit higher in calcium, phosphorus, and fat than usual. That being said, it was still 100% SAFE and met AAFCO standards.

We are thrilled to announce that the lot numbers affected by this are now out of production and the product you know, love, and trust is back on spec ready to help out your canine patients. Especially those with fat intolerant patients!

There were ZERO ingredient changes to get us back to our regular key paramaters. 

Please do not hesitate to call or email with any questions or concerns!

The Whole Story on Whole Foods!

Rayne diets are primarily made with whole food, less processed ingredients. Each individual bag or can of Rayne food looks distinctly different from the others: the texture, colour, and consistency reflect the individual ingredients that have gone in. Using whole food ingredients means there is more variability in appearance from batch to batch. Whole food ingredients vary in colour, texture, consistency, and density, just like when you cook at home. 

The experts on our Rayne manufacturing teams ensure that all of our incoming ingredients undergo extensive testing, right through production. Additionally, comprehensive in-house AND 3rd party (independent) analysis is done on each and every finished Rayne product to ensure we are delivering consistent and precise nutrition with each bag or can. 

This extreme dedication to quality and safety means each and every kibble and spoonful of wet food has been extensively tested for quality and safety before you feed it to your pet. 

Although our manufacturing team works very hard to minimize any changes, we expect to see variation in colour and size of kibble, as well as in colour, texture, and density of wet food. This is a reflection of the natural, whole food ingredients, and represents no concern for quality, safety OR nutritional precision. 

No two vegetables or fruits look exactly alike. Whole foods ingredients are just real food!

Rayne Canine Diets
Rayne Feline Diets

As a completely veterinary exclusive company, we will always be responsive to the veterinary market. We have had some great feedback about our size offerings. To simplify things, we will be transitioning from having a 2 and 4 kg size to one, unified 3 kg size. The price of the 3 kg represents a blend between the 2 and 4 kg cost/kg to ensure a fair and consistent price to the market. This will also be the launch of our NEW look for the small sizes. The changes in names and look also came directly from market feedback. We are thrilled to be able to respond to what you want to see in both our product names and package design. The first diet to transition will be the K9 Low Fat Kangaroo-MAINT (previously named Low Fat/Novel Protein-KSP). Please note that there are NO ingredient changes from the current formula. The remainder of the diets will transition over the coming months, beginning with K9 Rabbit-MAINT (previously named Novel Protein-RSP), K9 Growth/Sensitive-GI (previously named Sensitive-GI), and K9 Adult Health-RSS (previously named Urinary Protection-RSS). Feline diets will follow shortly after. Please continue to share your feedback! We want to work with you to bring the best offering to veterinary nutrition in Canada.
