[BLOG] #QuickFact : The Answer Might Be In The Bladder

🇫🇷 Lire en Français Ici 

I was writing an article recently on reproduction in the male cat.  

And it reminded me of a #QuickFact that you guys cat breeders would be interested in.  

We already touched on how difficult semen collection and evaluation is in the feline species.  

You can read my previous post on this here

There is however a quick and simple way to evaluate if a cat produces sperm.  

The answer is in its bladder.  

No, I’m not kidding ! 

In male cats in fact, nearly 50% of the volume of the ejaculate will end up in the bladder during ejaculation. 

We call this retrograde ejaculation.  

And you now understand that in male cats, it is quite common.  

If you check the male cat’s urine after breeding, that will help answer the question if this male produces sperm or not.  

It is not as good as a full spermogram, for sure.  

But it is still a valuable clinical information. 

That’s the #QuickFact I wanted to share with you today on cat reproduction. 


[BLOG] #QuickFact : The 35 Day Rule

🇫🇷 Lire en Français ici

I received an interesting email today.  

« I’m dealing with a pregnancy arrest in a bitch. Should I do something ? »  

How to answer this ? Well, remember the « 35 Day Rule » .  

In a bitch or a queen, pregnancy arrest that happens BEFORE 35 days post-ovulation will lead to embryonic resorption.  

Understand that dead embryos will literally be « digested » by the uterine walls.

You will see nothing. You might not even notice if you did not do an early pregnancy diagnosis.  

I wrote a blog on this, you can read it here.

If pregnancy arrest happens AFTER 35 days post-ovulation, you will typically observe an abortion.  

Which means that this time, YOU WILL SEE « something » – blood, organic debris,…- coming out from the vulva of the bitch/queen.  

In the case of an abortion, your veterinarian might need to help the expulsion of some of the material in the uterus.  

Typically however, this is not something required when dealing with an embryonic resorption,  

That’s what I call the « 35 Day Rule ». 

And it is the #QuickFact I wanted to share with you today on canine & feline reproduction.  

[BLOG] Remember this when it comes to calcium and growing puppies !


🇫🇷 Lire en Français ici

Every day, around forty nutrients should be provided in the dogs’ food. There should be enough of each nutrient [more than a minimum threshold] for the body to work at its best. However, is it beneficial to the health to have too much of any one nutrient? This is far from being certain, particularly considering that ALL nutrients are potentially toxic over a certain maximum limit which is specific to each one.

It is therefore unnecessary and even dangerous to add mineral and/or vitamin supplements if growing dogs are fed with a balanced commercial food.

[YOUTUBE] Dos and Dont’s on Parturition in Queens

🇫🇷 Lire en Français ici

I very often get questions on birthing in queens.

Nothing abnormal here : no doubt it can be a stressful moment.

Indeed, hard to predict with certainty what is going to happen when multiple kittens are expected !

As cat breeders, what should you do ? What should you NOT do ?

This is why we decided to give this webinar on parturition in queens.

Cat breeders from 12 different countries attended.

One thing I can tell you for sure : we had a very good online discussion !

If you missed it,  don’t you worry, you can still watch the replay, the video is right below !

And if you have stories / anecdotes / questions, post them in the comment section below !

I’m looking forward to reading them !

[BLOG] 16 things dogs breeders MUST know about pseudo gestation Part II

Part II

We started discussing pseudo gestation in canines in our previous blog (read Part I here). We discussed what causes it and why, in canines, it is not really something abnormal. Now time for Part II : let’s discuss prevention and treatment !

It was #BackToSchool this week. I used to love it when I was a kid.

And I was excited too this year.

Because I knew what it meant for me : #BackToBlogging.

[BLOG] Estrus Induction : Yes We Can in Canines

As I write those lines, I’m currently on a plane. Somewhere above Africa. On my way to Johannesburg. 

You’ll never know when inspiration strikes.

“I never see her in season Doc. Anything we can do about that ?” 

That is a discussion I had a long time ago with a dog breeder client. 

She was breeding Yorkies. 

And for one of her bitch, she was never able to detect when/if she was in season.

She called it “ghost heats”. I prefer “silent heats”. I think I even already write on this topic.

See my blogs here :

The truth about Silent Heats Part I

The truth about Silent Heats Part II

In my experience, silent heats are more often encounterd in small breeds. 
But to be fair, it can be seen in any sized bitch. 

Rule of thumb that you will often hear me say : “Everything is possible in biology.”

Coming back to our story : my Yorkie breeder was wondering how to deal with her silent heat situation.

Obviously, I had a few work-around solutions. 

Let just speak about one of them here : something we call “estrus induction”.

Estrus induction = medical protocol to initiate the bitch’s season. 

Yes. We can do that in veterinary medicine. 

Thanks to molecules called dopamine- or GnRH-agonists. 

I did my PhD on the late one. I remember how happy I was with the results. 

I even wrote a scientific paper on this. You can check it here.

What can you expect from these protocols ? Answers in the video below, in which I review them all.

When can we do that in the bitch ? 

Only when we are sure that there is no hormonal disbalance. 

There are a few preliminary tests (hormonal assays, ovarian ultrasounds) to ensure there is no contra-indications.

Like an ovarian cyst for instance.

Estrus induction can be attempted if there is none. 

It can lead to fertile heats. It helps obtain puppies. 

And in tricky cases like this one, it would be a great option. 

We can do pretty amazing things today. 

We have powerful tools.

They can help us achieve great results. When properly used.
