Do you recognise these changes in your dog?
Repeated scratching, scooting or a change in stools is worth paying attention to. Keep a note of the changes you see:
- Scratching or paw licking
- Scooting or dragging their bottom
- Loose stools or digestive upset
- A dull-looking coat
- Restlessness or changes in energy
- Changes in appetite or weight
These signs have several possible causes; they do not establish a parasite diagnosis. Your veterinarian can help identify the cause and appropriate care.

GUT HEALTH & EVERYDAY WELLBEING
A healthy routine starts with the gut.
Your dog’s digestive tract is home to a complex community of microbes. This microbiome helps with digestion, nutrient processing and normal immune function.
Diet, age, stress and medication can influence that community. Gut care works best as part of the bigger picture: balanced food, an appropriate routine and care tailored to your dog.
Fortiva combines botanical extracts with postbiotics in a daily liquid format. It is a supplement to that routine; persistent symptoms still need a veterinary assessment.

How soon should I expect a change?
Each dog is different, so there is no guaranteed timetable. Track the changes you are hoping to address and discuss ongoing or worsening symptoms with your veterinarian.
Is this the same as a prescribed dewormer?
No. Fortiva is a supplement. A veterinarian can identify a suspected parasite and recommend an appropriate treatment; do not replace prescribed deworming or prevention with these drops.
What if my dog’s parasite test was negative?
If symptoms continue, ask your veterinarian whether further investigation is needed. A supplement should not be used to diagnose an infection or override test results.
What does it taste like?
The formula uses natural duck flavour and is given by mixing the measured serving into food.
Does this replace veterinary care or prevention?
No. Supplements do not replace veterinary testing, diagnosis, prescribed treatment or your dog’s prevention programme. Speak with your veterinarian before making any changes.
