Separation anxiety in dogs can manifest itself in a variety of different ways, with varying severity.
High activity levels when you are gone – running between windows and doors
Very low activity levels when you are gone – laying in their bed but not asleep or relaxed
Barking or howling
Destructive behaviours, including scrabbling at the doors or at their crates, chewing or destroying items or furniture, tipping over bins and more.
Excessive drooling
Urination or defecation, especially if they are already house trained
Not eating food or treats left for them whilst you are out
Nervousness as you prepare to leave the house
