Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 2 months and 4 days old | 4 lbs
Can I administer Pet Armor Plus for small breeds 5-22lbs on my 9 week old paparanian when he is not quite 5lbs maybe half the dose? Or what would be safest for my sweet baby?
Hello, and thanks for using Petco Pet Education Center, formerly Petcoach. What a cutie!! I recommend sticking with a product that’s on label for both Nash Ford’s size and age. I really like Nexgard, which is labeled for 4 lbs and up, and as young as 8 weeks. It should be available from most vets.
Hope this helps! It’s great that you’re taking such good care of your sweet pup!
