Hello, was the collar one of the anti- bark collars that sprays citronella, or was it a herbal flea collar? Either way, the scent is likely repulsive to Topo and making him nauseated. You should take it off him and bath him well to remove the scent from his fur. Citronella is not toxic unless ingested then can cause vomiting. If the heavy breathing continues you should take him to a vet.
