Adaptil large collar
These collars are great for nervous/anxious dogs and Pacific Pet Supplies are the cheapest by far! Unfortuately Fastway couriers are letting you down. I ordered my collar on the 5th of December and it's now the 15th of December and I haven't received it yet- everytime I call them they have no record of my previous calls/delivery instructions. There's nothing fast or courier-like about their service- I would stick with offering your customers Australia Post/Express Post only.
Adaptil Collar for Pet Anxiety
My nearly 8 yr old rescue dog, Isla (Staff X Kelpie) has severe anxiety as well as being off-the-charts stormphobic. I've used the Adaptil collar since we adopted her 5 years ago. Her level of anxiety is so extreme we've been told this is as good as it will likely get. This product definitely takes the edge off, enough so that we get to keep more of the woodwork in our home as well as having a happier dog. Prior to mediation being prescribed for anxiety (some 6 months after adopting Isla), we used the collar exclusively. It was so effective in those stressful first months that we've continued using as well as her medication. I highly recommend this product.
