Where can I get affordable Nexgard for my dog's prescription?

You can find this product at any of the online veterinary pharmacies. In order to find the best value I would recommend going on goodrx.com. On this website you will be able to type in the medication and dose and it will provide you with coupon codes and the location of where you need to obtain the product. Regardless of what site you use you will still need to obtain a prescription from your veterinarian. I always caution my clients when they are planning to purchase these types of products from pharmacies of unknown origin as we cannot be certain how the drugs are being stored and what source they are obtaining the drugs from. Do your due diligence before deciding on which place to use. I have had relatively good experiences with Valley Vet Supply.

My dog gained weight. Is her Nexgard still protecting her from fleas?

She'll probably be fine for this month if she's just a pound or two over. But in the future, if she's gained a bit of weight and is now borderline or just over the maximum weight for her current dose, I would get the next size up. Nexgard has a very wide margin of safety, so the manufacturer recommends "rounding up" if a dog is near the upper limit of the weight range. :)

My dog reacts to NexGard & Advantix. What are safe alternatives?

You have a few options. If you want an all in one product, try Trifexis. Otherwise you will two separate products. You might try Simparica (fleas/ticks) and Interceptor (heartworm/intestinal worms). I also recommend to have Sparky's stool checked for worms in case that was a round worm. For that parasite, pets are often given bolus dewormings since people can get that worm. That will clear up the infection faster.

Does NexGard chewable prevent heartworm, or just fleas and ticks?

NexGard does not prevent heartworms but does prevent fleas and ticks. I use it on my own dogs and have been very happy with the product. Advantix or Frontline are also good products so you should use whatever you prefer.

Is it safe to give my dog Nexgard if Hartz flea treatment didn't work?

You can give him the Nexgard now. There is more you can do: 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 (Nexguard is great) 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.
