possible spay infection... 2 months later?

[Manathos22]

i'm worried about my baby.. she was spayed 2 months ago and she didn't have any infection while healing we went fishing yesterday and she wet swimming ...not for the first time but today she has a bubble right on the scar for her spay. it almost looks like when someone gets burned really bad and it blisters up...she is acting normal but it's just not like her to have random bumps that look like they're full of water on her

if anyone can help or has any guesses as to what it is than i would appreciate it...should i taker her to an after hours Veterinarian?

Abdominal incisions are closed in layers. Spays usually have two layers of sutures, one inside, to hold the abdominal muscles together while they heal, and then sutures, staples, or glue to hold the skin together. The sutures on the inside are made of a dissolvible material because the Veterinarian isn't going to open the skin up to remove them.

As these internal sutures dissolve, the body sometimes reacts to the material, and a serum pocket forms. It's not an infection, it's just a collection of fluid. Usually it's reabsorbed over several days. Serum pockets can be alarmingly large, or small and insignificant. A lot of strenuous exercise does seem to cause them to become larger, though.

Of course, it's still possible for an infection to be present. I'd let the dog's general health and behavior guide me to whether immediate attention is required or not. If your dog is acting normal, eating and drinking, urinating and defecating as usual, and there is no lethergy, vomiting, diarrhea or an unusual increase in water consumption, I'd wait and call my Veterinarian in the morning for advice.
