5 Rules for a Puppy

Five things that matter most in your puppy’s first year — food, fleas, vaccines, training, and dental care.

Seven day chart for transitioning a puppy onto new food, from the veterinary team in La Puente

1) Food

  • Puppy food until 10 months for small breeds, 1 year for large breeds.
  • We recommend Royal Canin® or Hill’s Science Diet®.
  • Change food gradually over seven days to avoid an upset stomach.

2) Fleas

  • We have fleas year round.
  • Use only prescribed flea medication.
  • Treat the pet and the property — adult fleas are only 5% of the problem.

3) Vaccines

  • No outside walking before 4 months of age, plus one week.
  • This applies no matter how many vaccines they have already had.
  • The 3 month and 4 month visits are the most important.

4) Training

  • Start noise aversion training before 5 months.
  • Play online recordings of thunder and fireworks at a low volume, so your puppy learns those sounds are nothing to fear.

5) Dental Care

  • Practise with a silicone finger brush at 4 months.
  • Move to a real toothbrush at 10 months, using an enzymatic paste.
  • Dental treats do nothing if they are finished in under five minutes.

Questions about your puppy?

We are happy to talk through feeding, vaccines, or when it is safe to start walks.

Feeding Schedule

How often and what mix to feed, by age. Feed until slightly pot bellied at each meal for the first months, then follow the guide on the bag.

Puppy feeding by age
Age Meals per day Canned / dry How much
2 months 4 × a day 50 : 50 Until pot bellied
3 months 3 × a day 75 dry : 25 canned Until pot bellied
4 months 2 × a day All dry Based on the bag

Changing food? Take a week over it

Mix the new food in gradually across seven days — roughly 25% new for days 1–2, half and half for days 3–4, 75% new for days 5–6, and fully switched by day 7. If your puppy needs longer, keep them on a mix until they settle.
