Training and socialisation
The AKC says that, as a terrier, it has quick intelligence, courage and liveliness, and as a toy breed it is small and devoted, with boundless love for its owner.
It responds well to rewards and consistent training. The AKC gives it 4 out of 5 for barking.
Tips for effective training
- Use rewards. It is intelligent.
- Teach it “quiet”. It barks quite a lot.
- Keep it at the right weight. Obesity is a problem in the breed.
- Keep it from making big jumps. For the sake of its knees.
Activity needs and lifestyle
It is a small but energetic dog that needs daily walks and play. The AKC says a healthy diet and exercise are essential, as obesity is a serious problem in the breed.
| Activity | How often | Why it matters |
|---|---|---|
| Walks | daily | Fitness |
| Play | daily | Energy |
| Tricks | several times a week | A busy mind |
Tips for a balanced life
- It suits an apartment.
- Keep it active every day.
- Brush its teeth regularly.
Care and health
Coat and skin care
The short coat needs very little care: a weekly brush. The AKC says the anal glands should be checked often and the teeth cared for regularly.
Common health problems
The AKC says the breed is generally healthy, but obesity is a serious problem. Breeders check for:
| Condition | Description | Common symptoms |
|---|---|---|
| Patellar luxation | The kneecap slips out of place | Suddenly holds a hind leg up for a few steps, then uses it again |
| Eye diseases | Inherited conditions | Poor vision |
| Obesity | A serious problem in the breed, according to the AKC | Weight gain, tiredness |
Other care
- Check the anal glands often.
- Brush its teeth regularly.
- Go for yearly check-ups.
Diet and nutrition
The AKC says a healthy diet and exercise are essential, as obesity is a serious problem in the Toy Fox Terrier.
Tips for a healthy diet
The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.
| Dog's weight | Calories per day (neutered) | Calories per day (not neutered) | Dry food per day (approximate) |
|---|---|---|---|
| 1.8 kg | 170 kcal | 200 kcal | 42–57 g |
| 3 kg | 260 kcal | 290 kcal | 65–83 g |
| 4 kg | 320 kcal | 360 kcal | 80–103 g |
- Measure its portions.
- Treats count towards the daily portion.
- A dog is at the right weight when you can feel its ribs without pressing hard.
Foods to avoid
Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.
Reproduction and development
Physical and emotional maturity
In dogs, sexual maturity usually comes between 6 and 12 months. Small breeds become adults faster than large ones, usually at around one year.
Mating and pregnancy
Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. Only healthy dogs of typical breed appearance should be used for breeding.
Caring for the puppies
In small breeds, a litter has 3–4 puppies on average. The puppies are very small and fragile in the first weeks, so they must be kept warm and handled with care. Socialisation starts early: gentle handling, everyday noises and new people.
