Frequently Asked Questions
What should I do if I think my dog has Lyme disease and it's after hours?
That's stressful, I know. If your dog is stable — eating, drinking, not in severe pain — you can wait until morning to call your vet. But if they have a fever over 104°F, can't stand, or are having seizures, head to the emergency vet. Deep breath — most dogs do fine with treatment.
My dog is limping but has no fever — could it still be Lyme?
Yes, it can. Some dogs only show lameness without fever, especially early on. The classic sign is a limp that moves from leg to leg. If it lasts more than a day, get a vet check. Other things like a sprain look similar, but Lyme is common enough to rule out.
How long after a tick bite do Lyme symptoms appear in dogs?
It usually takes 2-5 months for symptoms to show up. That's why you might not connect the tick bite you found months ago. But the bacteria can stay dormant. If you see signs now, don't wait — treat it.
Is treating Lyme disease expensive?
It can be a few hundred dollars for the vet visit, blood test, and doxycycline. But it's much less than treating advanced Lyme complications. Many owners find pet insurance helpful. The real cost is if you delay and your dog gets kidney damage.
Can my dog die from Lyme disease?
That's a scary thought. Most dogs recover fully with antibiotics. In very rare cases, Lyme can cause kidney failure or heart issues, but that's not common. The best thing you can do is get treatment early. You're already doing the right thing by asking.
Does my dog have a Lyme disease rash like humans?
No, dogs rarely get a bull's-eye rash. That's a human thing. In dogs, watch for lameness, fever, and tiredness. If you see a red spot at the tick bite site, it could just be irritation.
