9 week old puppy itching and biting herself .....
...... BUT she has had her 1st injections and been treated for fleas etc, 2nd injection coming up.
I bought my doberman two weeks ago off a home breeder, the lady said she had been flea and wormed, had her first injection and was ready to leave her mum and was healthy and been checked over from vet, lady had also said she had bathed the puppy the morning i picked her up so she smelt nice, the lady also gave me the pups vet card that had been signed from vet saying she had her first injection, note did not say she had been treated for fleas and worms.
When i got the puppy home 2 weeks ago i noticed something moving in her fur, so i took her straight to my vets, got her registered, my vet said she was a little under weight with a bloated belly which meant worms, so she got treated for worms, vet couldn't see and fleas but treated her for fleas as we didn't know weather to believe the lady who sold her to me as it wasn't signed by her vet.
When i got the puppy home that night i bathed her myself with a flea shampoo as she smelt not very nice, so didn't belive lady she had been bathed before i got her either.
NOW, she scratches and bites herself, she's got a few little bald patches coming up, little patches, one on her nose, a couple on her tail, and now some on her back.
She's not uncomfortable, a very happy dog who's running around, playing, eating and drinking all ok.
I also have a 18 month big golden lab who's up to date with injections and is treated every month by my vet for flea and worms.
It's possible that fleas have caused the itchiness that your puppy is experiencing, but if she's was treated 2 weeks ago for fleas then they shouldn't be bothering her anymore.
Intense itching is often a sign of allergies, fleas are one trigger, so are certain ingredients in dog food, or shampoos, or things that she comes in contact with. You can learn all about this on my Dog Allergies page.
As she is now developing small patches of hair loss it's possible that she's suffering from mange, which is caused by tiny skin mites. You can find out more about all of this on these pages... Puppy Hair Loss and Mange In Dogs
Your vet is the best person to help you with this so I'd recommend taking your puppy back to your vet for another exam. He can diagnose mange by taking a small skin scraping and also help with allergy testing if necessary.
It seems as though your pup didn't have the best start in life, but with lots of love and proper health care I'm sure she will grow up happy and healthy. Best of luck.
