Seizure vs. Muscle Spasms: Seizures can take on various forms in dogs, and some can be quite dramatic with convulsions and loss of consciousness. However, not all seizures look the same. Some seizures may manifest as muscle twitches, jerking, or spasms. These can sometimes be mistaken for painful spasms, but a veterinarian's evaluation is necessary to distinguish between the two.
Other Possible Causes: Seizures can have various underlying causes, including epilepsy, toxic exposure, metabolic disorders, or underlying neurological issues. Muscle spasms can also occur due to pain, injury, or other medical conditions.
Given the unusual behavior you've described, it's essential to consult with a veterinarian as soon as possible. They can perform a thorough examination, conduct any necessary diagnostic tests, and provide a proper diagnosis. In some cases, treatment may be needed, especially if the episodes continue or worsen.
Additionally, since you mentioned that you're currently facing financial constraints, consider reaching out to local animal welfare organizations, pet charities, or low-cost veterinary clinics in your area. They may be able to provide assistance or resources to help with your dog's medical care.
It's admirable that you've taken in your sister's dog and are committed to her well-being. The best course of action at this point is to have her evaluated by a veterinarian to determine the cause of her episodes and to ensure she receives the appropriate care and treatment.
