Yes puppies are born with worms and should be dewormed by 3 weeks.
I know that you can give puppies over 6 weeks old Safe-Guard® Canine Dewormer, but I have never used it.
If by puppy cat you mean kitten? Then the answer is usually no, but all worming products tell you quite clearly on the packaging what is a safe age for the animal.
No - at this age, your puppy has been completely weaned from his mother and no longer has the ability to digest milk sugars. You can cause digestive upset, including diarrhea, if you feed milk to a 10 month old puppy.
yes
no
I am assuming you mean " give a 9 month old puppy his first shots"Well , puppy should have had his first shot at 3 month, depending on the breed, some very small breeds get their shots at 4 month. But better late then never. Take this puppy to the vets as soon as possible, the vet will advise you what is needed and how to proceed.
if you are training your puppy then you should used soft treats but you can give you puppy any treat that is intended for puppies
you should probably ask an animal doctor.
You give the exact amount prescribed by your veterinarian. If your veterinarian has not prescribed penicillin for your puppy, you should not give any to your puppy. Penicillin is a drug with known side effects, including severe gastrointestinal bacterial infections from killing off the beneficial bacteria in the gut.
Puppy chow.
No, you should never give a dog or puppy of any age a pork bone, because if they swallow it, obviously, this will be very harmful to them and the bone can splinter. The actual pork meat would be ok to give to them.
