Congratulations on your new puppy!
I highly suggest you switch her food. Eukanuba is not a good food (full of corn, bi-products, fillers, artificial ingredients, etc). Whenever you do change a food, especially to a better quality or higher protein content, you want to do so slowly and over 7-10 days. Mix the old food with the new gradually and by day 7-10, she should be fully on the new food. Puppies have sensitive systems as well, and anything that isn't agreeing with them can cause them to have diarrhea. Also, vaccinations can cause their systems to go awry too.
If diarrhea continues, contact your vet. She could have picked up Giardia from the breeder.
I suggest you also add enzymes to her food. I use Total-Zymes and it is fantastic! I feed
Lotus to my dog and
Nature's Variety to my cats. Enzymes are good no matter what you feed.
Your best bet for a happy, healthy pup is to start her off right on high quality foods. My top list:
- Lotus
- Orijen or Acana
- Nature's Variety
Good luck and hope she feels better!
