I honestly doubt that your dog contracted lyme disease. How large was the tick that you pulled off of her? Are you sure it wasn't just a wood tick and not a deer tick? Generally deer ticks are very hard to find on people because they are so small, much less on a furry cocker spaniel. If possible can you see the skin around where you removed the ticks? Is there a bulls eye like rash?
Has anything else changed in her life? Food, environment? I would still take her to the vet tomorrow. Until them, stay calm and I hope everything works out for you!
