We have a 4 month old yorkie maltese mix. He was healthy up to 3 months old, now he started walking around following walls and bumping into things, he also has fluid running out his nose when this happens. He won't respond to anything is in a daze. He seems off balance, but can't stop walking. He's OK in the morning but gets worst through the day. Seem to happen after his 2nd vacine. Local vet don't know whats wrong.
Has your pet had any blood work? This sounds like a neurological problem. I recommend that you ask your vet for a referral to a neurologist. Maybe they can help. vetcare
