Is this an ultrasound of canines or humans?

My friend's ex is saying that this is a sonogram of their twins. Why would it say "canine" on it and are there determining features on the fetuses that could definitively say whether they are human or canine? Any help or extra info you can give would be greatly appreciated! (The story in his words from a different online post: My ex hasn't been able to accept our break up 2 months ago and she's now telling me that she's pregnant. She told me that she was going to an abortion clinic for an appointment (I suspected she was making the pregnancy up but in case it's real, I tried to discuss options with her and told her that I would do 50/50 custody if she keeps the baby but she kept insisting that because I don't want to be with her in a relationship anymore, that means I want an abortion which isn't true), and then after the appointment, she posted this picture on her facebook, saying she's 14 weeks 3 days pregnant. She called and told me that she's pregnant with twins but that the abortion clinic did the ultrasound and they don't give print outs of the sonogram and that is the only picture she took. She said she now has to wait until she's 19 weeks for an ultrasound with her doctor. My friend noticed that the top left of the image she posted says "abdominal canine" which seems weird. I'm trying to stay calm and tell myself that I just need to wait 5 weeks and see what happens but I feel so anxious and sick inside like she's holding me hostage and am just looking for any expert opinions/advice on the legitimacy of the only proof she's provided: the ultrasound photo.

Hello!  At times like this, I wish that I was a problem-page Auntie as well as a vet - I would have a lot to say about this situation!  However, this is not the place; you are asking me for veterinary advice.  In general, it is not unusual to see human identifiers on canine ultrasound scans.  This is because - especially in the past - human ultrasound machines were cheaper than specialised animal ones and vets might try to get hold of ex-NHS equipment to use in their surgeries.  However, I can't imagine a human hospital using pet ultrasound machines to scan babies, and even if they did, one can usually change the species.  Using one with 'canine' on it would be highly unprofessional and offensive to clients.  I know nothing of your ex and cannot tell the difference between the two species of embryo on an ultrasound scan.  However, like you, I have my suspicions.

Ps I cannot actually read the word on the top left of the screen;  I am taking your word for it.

Is it even possible to tell the difference between the two species of embryo on a scan like this? This is what is  visible at the top of the sonogram (I have a better quality image and used that to write it out):

Yes, the writing on what you have put up definitely translates that "this is the scan of the abdomen of a large dog."  This would be a very curious thing to type at the top of a woman's ultrasound, especially if professionally done, and especially if planning to send it to an ex to prove the viability of a pregnancy.  I am not an ultra-sonographer I'm afraid and do not know how to tell the difference between the two or at what age of embryo this is possible;  it is not something we are asked very often!  - I'm sure that there is an ultrasound specialist trainer somewhere out there who can tell you.  I can't see very much detail on this picture.  Babies don't have coccygael vertebrae, but I'm not sure at what age this becomes obvious.

I can't see this picture in very big detail, but if you look at the spine of the rhs baby, is there a 'tail' (coccygael vertebrae) going beyond the hips?

(Correction:  babies do have Cvertebrae, but they dont form a clear 'tail.'
