New pills my dogs are trying
My Chihuahuas were on Heart Guard but stopped eating them. They are also toothless so it was difficult for them! So, I searched for a pill that I could use that wasn’t chewable and small enough and found Sentinel. It’s small enough so I can hide it in their food and it seems to be working out fine.
Great service
I gave this product to my yorkie for most of her life. Vet wanted me to give my new puppy simpatrica trio 6 pills 136.00. I went back to sentinel. Chewy handled it all for me and shipped it fast.
Recent Purchase
This is a recommended product and I have used it for years. Now that my Vet does not dispense I am happy Chewy offers this convenient service. I ordered 2 boxes for an annual prescription but only received 1. I wish chewy had notified me before shipping so I could discuss this with my Vet and save on shipping.
Works as Expected
This product works as expected for my 6.5lb toy poodle by keeping the little critters from producing eggs on my pet. Altough it doesn't keep fleas/ticks away it keeps them from making more eggs. I just keep his coat low by getting him gromed often so I can visually inspect skin. Safe and effective
Heartworm Medication
It's nice to be able to receive these in the mail automatically. Didn't know I could do that. Thank you!
Sentinel Heartworm Tablets
My dog will absolutely not eat the chewable heartworm medication and I had tried everything. These tablets are small and can easily be hidden in something he enjoys eating. I am extremely pleased.
Heart healthy medicine
Sentinel keeps my lil' one's heart healthy. Vet approved.
Mini puppy challenges
This is the only heartworm medication that I could find for mini puppies. My puppy weighs 4 pounds. I didn't want to get her anything for dogs weighing up to 25 pounds or the like. I was concerned she would be over medicated.
Great product
Our vet had prescribed another product that was difficulty to get our picky dog to eat. We switched to sentinel tabs and it makes our life so much easier in getting the medication in our little feisty dog!
Keeping My FurBaby Healthy & Safe!!
Chewy contacted my Vet for this item very quickly in which resulted in me receiving the tablets for my FurBaby asap. No time lapsed which is a PLUS! Recommend this - YES
