My dog has flea/fly allergies. Is Seresto better than Hartz collar?

Seresto is a very good product and in my experience would work best. Otherwise it seems you are doing everything Nina needs. Benadryl and any other medication you are giving should be ideally supervised by your veterinarian. Hope that answers your questions, if not please contact us again!

Can I use Seresto collar with Advantage or Frontline for my dog?

It is ok to use Seresto along with other topical products, just not oral ones. In some pets there can be a little skin irritation, so watch out for that and notify your vet if this happens. Otherwise, you should be fine to go ahead with Seresto to see if this does the trick. I would also recommend using a flea fogger to treat your home, which can be found at your local Home Depot or Lowe's. If you still don't have good results with the Seresto collar, then I would wait at least 2 weeks and consider better products such as Simparica or Nexgard. Best of luck with your flea issue and Nova moving forward. Take care!

Seresto isn't working. Can I use Frontline or oral flea meds too?

Please do not feed garlic to your dog, it can cause blood disease in dogs! Here are instructions for flea prevention: Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust., Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas. Flea products: Spot-ons and/or chews Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks a

My 18lb dog is borderline. Which Seresto collar size is best?

I would try the one for small dogs first, since Cinco is right on the border between weight groups. Seresto is very safe, so if the smaller collar isn't as effective as it should be move up to the large dog collar.
