Thank you. Give me a moment to take a look, please...

Expert:  Dr. Michael Salkin replied 1 year ago.

The photos are in shadow and so assessing the skin itself is difficult but I can see swelling of her inguinal mammary glands which would be consistent with false pregnancy (pseudopregnancy, pseudocyesis) if she were in heat 1-3 months ago and not bred. Is that the case, please?

over new year she was in heat, no she's never been bred or been near a male dog. Would you like me to send another picture?

See this picture attached

Psuedopregnancy, then, is the cause of the swelling. It should abate within 1-3 weeks unaided although in some dogs it can persist until the next heat period.

Yes, I'd like to take a better look at her skin. Can you photograph it with her lying on her back?

Customer: replied 1 year ago.
These pictures hopefully will help
Expert:  Dr. Michael Salkin replied 1 year ago.

Excellent photos, thank you. There's a focal hyperpigmentation associated with her right inguinal mammary gland skin. I can't tell if the skin is otherwise quiet in the photo. If it is, the skin hyperpigmented due to the elevated temperature associated with inflammation of that gland. If the skin isn't quiet - papules or pustules are present - the pigmentation is due to a chronic superficial spreading pyoderma (bacterial skin infection) which can be addressed with an over the counter shampoo containing chlorhexidine and a systemic antibiotic in the cephalosporin class such as cephalexin dosed at 20 mg/kg twice daily for 3-4 weeks and 1 week past clinical signs. The antibiotic would need to be prescribed by Pearl's vet. Please continue our conversation if you wish.
