Meet Delphie

Delphie is one of Guide Dogs Victoria’s friendly Ambassador Dogs and a familiar face at community events. From greeting visitors and posing for photographs to meeting supporters, she plays an important role in representing Guide Dogs Victoria and helping raise awareness of its services.
Like all working dogs, maintaining good health is essential to supporting her daily activities and overall wellbeing. This includes caring for every aspect of her health, including her teeth and gums.
Because Ambassador Dogs spend so much time interacting closely with people, maintaining good dental hygiene forms an important part of their ongoing preventative healthcare routine.
Why Dental Health Matters for Working Dogs
Working dogs rely on their overall health and comfort to perform their daily roles. Good oral health contributes to normal eating, comfort and general wellbeing, making it an important part of routine preventative care.
As one of Guide Dogs Victoria’s Ambassador Dogs, Delphie regularly participates in community events and spends considerable time interacting with visitors, volunteers and supporters. Maintaining healthy teeth and gums helps support her comfort and complements the broader health care practices already in place.
Like many aspects of preventative healthcare, dental care is most effective when it forms part of a consistent daily routine that includes veterinary monitoring, balanced nutrition and appropriate home care.
Why This Case Study Was Conducted
Houndztooth Dental Health Supplement was incorporated into Delphie’s established daily oral care routine from 23 October 2025, with observations continuing on an ongoing basis.
The purpose of this case study was to document:
- how the supplement was incorporated into an existing daily routine
- Delphie’s acceptance of the supplement when added to her food
- factual observations recorded by her handler and Guide Dogs Victoria staff
- the importance of maintaining a consistent preventative dental care routine for working dogs
Throughout the observation period, Delphie’s existing veterinary care, tooth brushing routine and balanced diet remained unchanged.
This case study documents real-world observations only and should be considered alongside regular veterinary advice and ongoing preventative healthcare.
Delphie’s Existing Care Routine
Before the observation period began, Delphie’s dental health was already supported by a consistent preventative care routine developed by Guide Dogs Victoria.
Her established routine included:
- Regular veterinary dental monitoring
- Daily tooth brushing
- A balanced diet
- Ongoing preventative healthcare
- Routine observation by her handler and Guide Dogs Victoria staff
These practices remained unchanged throughout the observation period, with Houndztooth Dental Health Supplement added as an additional component of her daily routine.
Introducing the Supplement
During the observation period, Delphie’s handler incorporated Houndztooth Dental Health Supplement into her breakfast as part of her normal daily routine.
The supplement was added alongside Delphie’s existing preventative healthcare practices, including daily tooth brushing and regular veterinary monitoring.
Delphie readily consumed the supplement when mixed with her food, allowing it to be incorporated into her routine without changes to her normal feeding habits.
Houndztooth Dental Health Supplement is formulated with carefully selected ingredients designed to complement everyday oral care. It is intended to be used alongside balanced nutrition, regular veterinary care and appropriate at-home dental hygiene practices.

Preventative Dental Care
Good dental health is about more than maintaining clean teeth. It plays an important role in a dog’s overall comfort, wellbeing and quality of life.
Plaque and tartar can build up gradually over time, often without obvious signs in the early stages. Regular monitoring helps identify changes before they become more significant, supporting long-term oral health.
A comprehensive preventative dental care routine may include:
- Regular veterinary dental examinations
- Daily tooth brushing where appropriate
- A balanced diet
- Routine monitoring of the teeth, gums and breath
- Nutritional supplements that complement an established oral care routine
Every dog is different, and the most appropriate approach will depend on their age, breed, health status and individual needs. If you notice persistent bad breath, inflamed gums, difficulty eating or other changes in your dog’s oral health, seek advice from your veterinarian.

- A balanced, nutritious diet

- Nutritional supplements that complement your dog’s oral care routine
If you notice persistent bad breath, swollen or bleeding gums, difficulty chewing or changes in appetite, consult your veterinarian for advice.
