Why wobbliness means immediate vet action
An unsteady gait in your 8 kg beagle confirms the solanine from those green tomatoes and leaves is already affecting his nervous system. This isn't a 'wait-and-see' situation—neurological symptoms like loss of coordination indicate the toxins have reached his bloodstream. The timing (one hour post-ingestion) suggests rapid absorption, which is common with solanine in dogs of his size.
While waiting for veterinary instructions, minimize his movement to prevent falls or injury. Dim lights and quiet surroundings help reduce sensory stress while his system fights the toxins. Note whether his wobbliness is constant or comes in waves—this detail helps the vet assess severity.
What the vet needs from you right now
Prepare to describe the exact plant parts consumed: were the leaves young and tender or older and tougher? Did he swallow chunks of unripe tomato with seeds? These details help estimate solanine load. Since he's a beagle—a breed prone to enthusiastic chewing—mention whether he actually swallowed material or just shredded it.
His 8 kg body weight puts him at moderate risk for solanine poisoning compared to larger dogs. Expect the vet to ask about pre-existing conditions like seizures or liver issues that could complicate treatment. Have his vaccination records handy in case sedation is needed for diagnostics.
The critical next six hours
Even with veterinary intervention, neurological symptoms may temporarily worsen before improving. Muscle tremors or dilated pupils could develop within the next few hours. These don't necessarily indicate treatment failure—solanine runs its course as the body metabolizes it—but do require professional monitoring.
Hydration will be a priority if vomiting or diarrhea starts. Unless directed by the vet, don't offer food or water until his coordination improves—aspiration risk is high with wobbly patients. The clinic may administer IV fluids to support kidney function during toxin clearance.
Longer-term recovery expectations
Most dogs show noticeable improvement within 12-24 hours with proper care, but full recovery may take a few days. Your beagle might seem unusually tired or have a reduced appetite during this period. These are normal as his body recovers—what matters is that the wobbliness doesn't return after initially improving.
Going forward, consider fencing off garden tomatoes or training him to avoid nightshade plants. Dogs who've experienced solanine poisoning sometimes develop aversions to the smell, but don't rely on this—supervise all outdoor access until you're confident in his avoidance behavior.
