https://www.vetsurgeon.org/f/clinical-questions/2327/neutering-of-bitches-with-delayed-first-season A case recently brought up a few questions regarding bitches which are delayed in having their first season. How old are they before you do something &amp; what is it you do? (spay regardless, blood tests etc..) To an extent this will be affected by sizeen-USTelligent Community 10https://www.vetsurgeon.org/thread/4168?ContentTypeID=1Tue, 05 May 2009 22:42:26 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:e2741922-6bb3-46b0-94ea-fa5da3182317Mark Frost<p>I think that comes from being a Bristol grad under Professor Holt, as far as I am aware no studies back it up yet (but may have missed something in the last few years).&nbsp; Its practice policy here but potentially needs discussing...</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/4154?ContentTypeID=1Tue, 05 May 2009 13:03:13 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:8d5d7e44-dc3b-4191-902b-86e7631fae1bbeldather<p>I&#39;m interested in the statement of spaying after the first heat to reduce incontinence.<br />I have always been taught that you will actually get a reduction in UI by spaying prior to first heat as well as significant reduction in mammary tumours. The incontinence does however tend to be worse if it does&nbsp;occur. <br /><br />Always happy to change my mind though if the evidence is there.</p> <p>Regards</p> <p>Blair</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/3829?ContentTypeID=1Mon, 20 Apr 2009 13:12:53 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:c884855e-eb3e-4213-8c2f-3ef91d1e78afKevin Castle<p>Adult vulva and mammary development certainly suggests there has been some sort of season. I tell owners it&#39;s a &quot;silent heat&quot; and are happy to spay as long as there are no obvious signs of false pregnancy present. We too wait 3 months after season before spaying. &nbsp;A progesterone assay would rule this in or out.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/3816?ContentTypeID=1Sun, 19 Apr 2009 12:29:44 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:9c47920f-a580-4622-a894-02f396cb79a6ms1083<p>I would say that so long as she is not in season on the day of the op would do it anyway. If she has not had a season shurely the only problem would be slightly increased risk of incontinence later in life.</p> <p>As a practice we do them 3m after first season so they benefit of the season for the bladder sphincter but still have benefit regarding reduced mammary tumour development. The ones I have done before their first season are simple as the tract is tiny.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/3807?ContentTypeID=1Sat, 18 Apr 2009 00:11:28 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:caaaa792-05b3-45b1-9526-e453847e0e13Evelyn Barbour-Hill<p>Missing small premolars are very common so I don&#39;t think that tells you anything.</p> <p>What increased risk exactly is it the owners are worried about?</p> <p>&nbsp;</p><div style="clear:both;"></div>
