9wk JRT breath/chew toys smell like urine

This is our first JRT "Spike" who is 9wk old male. His health and play is excellent and fitting in quite well especially with our 15y/o son. No apparent undue stress. Recently we've noticed his breath and chew toys smelling like urine. His appetite is fine and drinks normal amt fresh water. His coat is healthy with no offensive body odor. Never have we seen him eat his feces or drink his urine. What can be causing this? I checked your FAQs before posting this but could not find anything closely related. Any help would be gratly appreciated.
