Fit 'n Fertile™ dog supplements

Are you giving your dog the best?

Ordinary "complete" dog food includes the basic food requirements, at a budget price.

But does it include the very best ingredients that your dog needs for first class health, and a fully fit and fertile, long life?

We believe in providing your dog with the very best formulae for dog nutrition. We use top-quality ingredients, prepared under carefully-controlled conditions. It may cost a little more than basic dog foods or cheap supplements, but you get what you pay for in this life: there's no such thing as a free lunch.

If your dog is “Man's Best Friend” then your dog deserves the best in return.

Our products help to improve your dog's condition and fitness, food digestion, gut health and disease immunity; keeping it fit and fertile.

If you show your dog, or if breeding is important, then it needs to be in the best of health. Suckling bitches need a boost to provide the best milk for their puppies. And suckling pups need a little extra help in those first few weeks of life.

Newline have been consultants to the animal feed manufacturing industry for nearly 20 years, so we know what we're talking about.

Our range of products cater for various dog conditions. See our Product Range page, where you can choose the right dog supplements formula for your pet, and see how much to add to their food or drink.

All our dog supplements are tried, tested and proven. Top breeders and show dog owners testify to the excellent results that our dog food supplements bring. We have countless satisfied users across many countries, including CRUFTS winners. See Dog Owner Testimonials.

We want you to see the difference, and we want you to know that you are doing the best you can for your dog.

Keep your dog fit and fertile with Newline - carefully designed supplements for dogs health care.

Technical Talk

Scientific research tells that improving the daily health and wellbeing of our dogs is important. This is best done by means of daily feeding - we need to improve food digestibility, gut health and disease immunity.

Daily improvements in these areas result in longer lifetimes for our dogs.  As humans, we take research seriously when it comes to our own food requirements. We know that dietary products are available, and we accept the extra cost in the interests of our own better health and wellbeing.

So, why not for our dogs too?

Newline Canine Supplements have been formulated to make these special extras available for dogs. If we enhance the normal diet with these "extras" from the biotechnology industry, our dogs can stand out in terms of improved dog health, vitality, condition and breeding, so that you can be satisfied and proud to show off your dogs to other admiring dog owners. (True story!)

Newline is also a consultant on nutritional and feed formulation to animal feed manufacturers in mainland Europe, Asia, and South and North America.
