Hyperattachment after a change or a rehoming

What this tends to look like

• Shadows one person constantly, room to room
• Cannot settle unless in physical contact or touching a door you are behind
• Distress at any separation, including you going to the bathroom
• Often a recently rehomed dog, or one who has lost a person or a companion animal
• Sometimes previously fine when the household routine was different
• May not have been left alone at all yet, so nobody knows the real tolerance

What is usually going on

A dog who has just changed households, or lost a member of one, is doing something reasonable: attaching hard to whatever appears stable. The mistake is to interpret it as devotion and accommodate it, because constant contact prevents the dog from ever discovering that separations are survivable. Six weeks of never being alone builds a dog who genuinely cannot be alone.

The work here is gentler than full separation training and it starts inside the house. Being on the other side of a baby gate while you cook. Being in a different room for two minutes. A settled place of their own that is theirs rather than yours. These in-house separations build the same tolerance without any of the risk of a real absence going wrong, which matters because a rehomed dog with one bad experience of being left can be set back a long way. It is also worth knowing that the first few weeks in a new home routinely look worse than what the dog will settle into. Judging a rehomed dog's separation tolerance in week two is judging them at their worst.

What you can do at home

• Start with in-house separations: a baby gate, a closed door for two minutes, you visible but not reachable
• Give them their own settled place, with their own bedding, and feed them there so it becomes valuable
• Do not sleep with them if the goal is independence, and be consistent about it rather than alternating
• Practice going to another room for a minute at a time, many times a day, long before you attempt a real absence
• Keep the daily routine identical while everything else is new. Predictability is doing the work
• Give it six to eight weeks before you conclude anything about a rehomed dog's baseline

What progress should look like

How long to give this before you conclude it is not working.

• First two weeksExpect this to look bad. A new home is genuinely destabilizing and it improves on its own.
• Two to four weeksIn-house separations should start to be uneventful. That is the milestone to aim for.
• Six to eight weeksMost rehomed dogs have settled substantially. This is the point to judge the real baseline.
• Beyond thatStill unable to be in a separate room after two months means it is worth involving a behaviorist early, before a bad absence sets things back.

When to stop and call your vet

• Any panic severe enough to risk injury or escape during an in-house separation
• Not eating over a sustained period, or losing weight
• Aggression when someone tries to leave, or when they are moved off a person
• No progress in in-house separations after two months
