None of Dylans belongings that could carry his scent was available in the first days of the investigation. But the
family had articles of the boys clothing delivered on the weekend.
We have the
clothes, Bender said Monday. We dont need them here (at the reservoir), but can use them later.

It is my understanding that because Dylan had
all of his clothing/everything with him when he disappeared, there was nothing that could carry his scent in the first days of the investigation. Furthermore, apparently the couch, pillow, blanket he reportedly slept on/used were not candidates for scenting for whatever reason. I believe there was also a statement in MSM that there were some articles of clothing left behind; however, apparently these, too, were not good candidates for scent.
I seem to remember reading somewhere, and will try to find a link, that MH was asked to bring some of Dylan's clothes to Vallecito, which seems to coincide with Bender stating that "we have the clothes". They had to have been clothes from his Colorado City home since Dylan had everything with him and it was stated they didn't have anything available for scent.
As far as the search, in the last thread I posted some links/information about the initial search of MR's home where they stated it wasn't a very thorough one - there were just looking to see if he was there and for his cellphone, and then some days later they re-searched MR's home with a warrant and did a more thorough search (i.e. took vehicles, Nerf football, sweatpants, etc.).
I have seen nothing in MSM about any search of ER/MH's home in CS. I would love to know if they did do that! If anyone knows, please share!
