Puppy and pressure treated lumber - Page 1

I am building a small 120 sq ft shed to double as the whelping room when the occasion occurs.

It will have PT lumber sill, the very bottom plate that comes into contact with the concrete floor.

Do you think pups will chew on the PT lumber enough to be harmed?

Thanks

HDG,
  We recently added another section to our kennel...That also was a big concern of ours...We got our materials at Lowe's and questioned them thoroughly concerning that....The lumber professionals there told us that a couple years ago, the government made it mandatory that all lumber if treated,  be certified to be harmless to humans and animals...

So it was my understanding that ANY lumber that is treated IS harmless to animals and humans...ITS THE LAW....

So go buy (4) 12' sticks of 1x3 and cover the bottom sill of the walls.

 I would not use pressure treated lumber in any area where your puppy / dog can chew on it. Consider this, they pressure treat (inject) lumber with chemicals to deter termites and wood rot.

If you have to use wood I would use cedar.

Here is a link to the risk review. Remember, it's Calcium Copper Arsenate not sugar

they use aresenic in pt lumber.   I would not use it.  As far as the big box retailers, at least over here, they do not cut any pt lumber in the store - for a reason. 

A couple of things........................ Is your only concern having P/T as the floor plate due to the contact with cement? If so then there are other options. The only reason using P/T against concrete is for moisture being wicked up into the lumber or standing water being an issue. Here are other options and you can decide by cost effective, labor intensive or aesthetics. Bottom line should be what works.

* Horse mat: use that as the same or a little under the dimension of say the 2X4 if that's what your using?
*Any PVC material boards; Azek, COMA and just cut it a half inch or so less than the 2X4 or whatever lumber your using. Floor plate rests on this.
* Say if you want some spaces/openings for washing/spraying out the floor. You can space bricks and rest the floor plate on them and secure with a "Timber Tech" screw and tie into the front and back structures
Use any wood the is water resistant for the floor plate; cedar, ipe etc. But usually any type of weather resistant lumber will be more expensive.
* As long as there is no "standing water" you can use any material that will keep the floor plate OFF the concrete.  

Thanks

I think I will put in 14.5 inch untreated  2x4  spacers to cover up the PT lumber.  

Here is information on the NEW pressure treated wood, since 2002, which no long contains arsenic compounds, but uses copper instead, which has its own issues
