Again, it depends on your pet, the area you live in and the level of risk involved.
These are things you should discuss with a veterinarian when you bring your new pup in for it’s first vet visit which is recommended within 2 weeks of bringing him home.
You should not accept a puppy that is less than 10 weeks old. You should not apply or give a puppy any preventatives without consulting a vet first.
Ps: Collars are effective as tick control for some dogs. Again, discuss with a veterinarian and come up with an option you are comfortable with.
No one should recommend specific products for you. Different products are best for different dogs.
