Hello, this is Dr Linda, a UK based vet.
I'm sorry to hear Honey is experiencing a phantom pregnancy as I know some dogs can become quite uncomfortable and out of sorts.
We advise waiting until the pseudopregnancy is completely finished to spay, otherwise we can cause signs to persist by spaying too early.
Personality changes and new behaviours aren't uncommon due to the hormonal surge. Some dogs become extra clingy and anxious, while others may even act possessive and aggressive.
Her new sitting habit and desire to be very close to you is likely caused by mild anxiety. You may find a few things help such as:
- Starting a few days of calming supplements such as Zylkene
- The use of an Adaptil collar or plug in
- Encouraging lots of exercise and brain games such as scent work, agility and training. Obviously, just what she is up for, as she may feel a bit lethargic.
- Keeping her occupied with food puzzles and chews
Some bitches feel nauseous and this can lead to panting and a slight appetite decrease. You may find a few days of a bland diet such as chicken and rice helps.
The snorting is not expected and I'm not sure what that could be. I don't suspect it is linked to her false pregnancy. She may have something else going on such as a mild viral infection, foreign body (such as a grass seed) in her nose or allergic rhinitis (like hay fever). If this persists, it is best if she is examined by a vet.
For most dogs, symptoms pass and no treatment is needed. However, if she is really not enjoying life and the false pregnancy is sticking around, there is a medicine available your vet can prescribe. As the medicine can cause side effects, we only use it when necessary.
