I know Border Terriers have a tendency to spontaneously start "singing". Whether you consider what comes out of them as singing or just howling is a matter of opinion but mine has started howling at around 12 to 13 years old. I guess in the immortal words of Eric Morecambe, he sings all the right notes, but night in the right places! I am informed that it may be dementia setting in. He seems OK in every other respect. I tend to blame Covid. The restrictions we were faced with basically threw us all together for abnormal periods and I guess now we are paying a secondary price. Its possible it is some sort of separation anxiety, which I could sort of understand if one of us wasn't in the house. But he starts as soon as I go out of the room now. If my wife has to go shopping, and I remain behind, he starts his routine. I watch him sometimes and occasionally he actually looks as though he's enjoying his aria, but other times it sounds woeful and as though he's distressed. What do I do? Is there anyway of reducing this as its driving us crackers! Although he doesn't look his age, he can't be walked long distances anymore because of age and a previous injury. Plus he has developed a heart murmur that although doesn't need medication, we are monitoring closely.
