Hi Bella and family, welcome. Sorry you had to join our club but we hope we can help you feel better about her recovery and life on three. If she hasn't perked up today let your vet know, just in case. Don't panic.

Many dogs have a little setback after looking really good after surgery. Typically it's because they are getting in too much activity too soon. Do tell us more about what her daily life looks like right now. Are there other dogs in the house that she may be playing with too roughly right now? Is she doing any walking other than going outside to potty, on leash? Also, I notice in her adorable avatar that you have hardwood floors. Have you put down throw rugs or carpet runners for traction ? Slippery floors are a Tripawd's worst enemy and walking on them can be exhausting. If she doesn't have a place to get a grip under her paws, she is basically ice skating all day long, which is really hard for any Tripawd but especially a new one. Be sure to pick up our Tripawds e-books for lots of tips about life on three. Our Tripawds Gear Blog and Jerry's Required Reading List also have tons of mobility tips.

My guess is that she may have just pulled a muscle and needs some really serious R&R and maybe a bit more pain control. Ask your vet about that part, don't change anything without asking them. What's her Gabapentin dosage and frequency right now?  

The possibility of infection is also there, but don't jump to that just yet. Is her incision warm to the touch? Any drainage? If so, what does it look like? How's her appetite? Is she eating, drinking and eliminating? All of this info is good to have before you talk to the vet, but don't wait and do it today. Then let us know what happens.
