Can Petco help me find accurate medication dosages for my dog?
Unfortunately, we are not permitted to give out drug dosages without a veterinarian - client - pet relationship. If you are seeking this information, I would obtain it through a veterinarian in person or through a veterinary formulary such as Plumb's or Merck. Hope this makes sense.

How do I prepare my sick small dog's vet-prescribed medicine?
Hi, thanks for using PetCoach! Unfortunately you didn't provide your dogs weight so we can not give you doses. I recommend calling your Vet when they re-open. In the US it is not legal to prescribe medications with out a label and the medications not reconstituted (made in to a liquid from the powder form). Are you in the US? Also in the US we do not prescribe Acetominophen ( https://www.petcoach.co/canigive/dog/tylenol/ ). I recommend calling your Vet regarding that medication as we can't recommend giving it to dogs. I am sorry but if you want to re-post with Ringa's weight we can probably help with the Amoxicillin).

How can I compare prices for my pet's prescription medications?
We don't sell prescription drugs here since we are only a consulting forum. However, if you want to do comparison prices for drugs then the best resource is https://www.goodrx.com OR calling the pharmacy of your choosing directly. I wish you all the best and hope that you can find an affordable price for your pets medication. Take care!

Vet Q & A
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.
