<p>In the published article, there were two errors in the main text.</p>
<p>A correction has been made to the section Results, Substrate diversity and modifications to substrate use based on performance, paragraph 1.</p>
<p>This sentence previously stated:</p>
<p>&#x0201C;When substrate diversity was divided into binary categories&#x02014;dogs with less substrate diversity (&#x0003C;3 substrates in training regimen) vs. dogs with more substrate diversity (&#x02265;4 substrates in training regimen), there was no impact of substrate diversity on the Relative Risk of TI or CI (<xref ref-type="table" rid="T1">Table 1</xref>).&#x0201D;</p>
<p>The corrected sentence appears below:</p>

<p>A correction has been made to the section Discussion, paragraph 15.</p>
<p>This sentence previously stated:</p>
<p>&#x0201C;For example, 51.5% (141/274) of dogs with experience training on &#x0003C;3 substrates were reported to have at least one MDP on natural grass, while 81.8% (27/33) of dogs with experience on &#x02265;4 substrates were reported to have at least one MDP on natural grass.&#x0201D;</p>
<p>The corrected sentence appears below:</p>
