What is Rubberwood?

"Rubberwood is a light-colored medium-density tropical hardwood obtained from the Pará rubber tree (Hevea brasiliensis), usually from trees grown in rubber plantations.[1] Rubberwood is commonly advertised as an "environmentally friendly" wood,[2] as it makes use of plantation trees that have already served a useful function."

I don't use flea collars, but my best guess is that they run by neck size. Measure your dog's neck then go to the pet store and look at the package to match them up. If that's not right, I'm sure the employees at the pet store will be able to help you determine the right size.

Hope that helps.

https://en.wikipedia.org/wiki/Rubberwood. Instead of using flea collars I use the 3 month flea and tick program by Bravecto it is a chewable tablet.I have not had one issue with fleas

In what context are you asking about Rubberwood? Measure the dog's neck and that should tell you what size to get.

I would not want a flea collar on my dog. Unless they've improved over the years, they really don't work. Why not use something like Frontline? It works.

dog groomer here. My experiences w dog flea collars are don't use them if another option will work. Mainly because a lot of dogs are sensitive to the chemicals in them and it can cause a chemical burn. However, sometimes a collar is just the easiest answer. Don't go by neck size. Most of the collars are sized way too big and you just cut off the excess. You want to make sure you are getting the right size of collar depending on what your dog weighs. If you put a large dog collar on a small dog you are exposing them to way too much of the flea killing chemicals. I recommend Seresto collars. They are more expensive but last many months and they're waterproof!

i would recommend the small, up to 18 lbs. it's close enough.

Contact your vet, my Bostons skin is sensitive so I have a monthly dose of medicine I got from the vet

I agree. Please go to the vet for medicine. Fleas are bad for your dog and for you. The medicine may seem pricy but in the long run it's worth it. Good Luck

A quick way to get rid of fleas at first, is to place the dog in a tub of water, maybe attach a stick close to his nose/mouth, and submerse him sloe to completely, leaving enough space for him to breath, but hold him under water for quite some time.

Coyotes do this with a stick in their mouth, and the fleas do not like water, so they move towards the dry areas. Then when they find none, they get on the stick.

You can also invest in some salt in a fair sized package, and add it to the water, mix it good and bathe them in the salt water, as that kills the fleas and their eggs.

Seresto Flea Collars work I have them on my cats. Although expensive when gotten from the veterinarian. I was going to get them on line because much cheaper. But all they have are Large & Small Sizes. That is why I was wondering what size to get for a Boston Terrier that weighs about 20 lbs.

I would say small the seresto colors work great work 8 months so it's worth the money.

Sorry collars

How about switching to Nexgard which works well for Fleas and ticks and it comes in pill form
