Ddandmydog,
Forgive this very long post (if it will let me post!) but I try to put info here that might help you or others, as you get to grips with OCD in your family.
I sincerely empathise with you and your daughter. I'm sorry to read in your initial post that your daughter developed a severe disability which has changed your lives. It's interesting that you say OCD manifested alongside this.
While OCD and OCD-Related conditions generally seem to have a genetic component, with structural changes in areas of the brain seen in fMRI studies of people with OCD and OCD-R sufferers, and in their first-degree relatives who themselves do not present symptoms, there can be other causes:
-OCD can develop in response to a stressful event (a new and severe disability onset could be a trigger in this respect)
-OCD can be induced by certain medications/withdrawal from medications.
Some medications, especially neuromodulating drugs (e.g. anti-psychotics, anti-epileptics, stimulants like ritalin, etc.) can cause OCD symptoms in people who had not previously experienced these.
-OCD symptoms can onset after streptococcal infection (Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus (PANDAS))
OCD can present in various ways; in milder or more severe forms of those types, and symptom development/severity can change over time, and be gradual or rapid onset.
Therefore, may I suggest the following: Keep an OCD /health status diary for your daughter and in it:
(1) Construct a timeline of onset
-Which came first - the disabilty or the OCD? [or did they co-occur?]
-What age was your daughter at time of onset of OCD?
-What age was your daughter at time of main disability onset/diagnosis?
-Did your daughter have strep-infection before onset of OCD?
-Did the OCD symptoms develop gradually over time, or were they very sudden onset?
-Have symptoms increased in severity or are they stable over time? (ie. do you notice an increase of washing, avoidance, crying, distress, complaints in time since onset or steady-state).
(2) List 'contamination triggers' and when they occur (date and time) and under which conditions
e.g, after eating certain foods, after taking medication, stressed going to school, while bored, watching tv, after spending time on her phone/ laptop/ ipad, etc. -so you can see if a pattern of onset and temporal occurrence is evident.
You mention other people touching her, cannot have different types of food touching on a plate, requires individual toothpaste tube, dog: sound of eating, contact with fur /drool, is there anything else? -add to list and note date/time and circumstances of occurrence.
(3) Medications:
-Is your daughter on medications for her disabilty?
-Did the OCD manifest after starting medication?
-List all the medications and vitamin supplements your daughter is on - their name/brand, exact dose, frequency (eg.daily / three times a week, etc.), start dates (if known or to nearest month/year)
-check if her symptoms increase or worsen after taking any given medication (eg. worse within an hour, a day, etc.)
It is worth reviewing your daughter's medication (if on any) with your GP/specialist to see if any of her medications might be implicated in development/worsening of OCD symptoms, or if the dose of meds may be adjusted to see if symptoms abate. Drug-induced OCD can also occur after cessation of certain medications, as a withdrawal response.
(4) Talk to your daughter about what she feels about her triggers:
-is it a physical sensation of touch she detests (like a sensory processing issue when someone touches her, certain fabrics, the feeling of dog fur/drool on skin)
-or is it a fear of contamination by unwanted touch of an object/uncleanliness?
-or is it a fear about something else/someone else and 'avoidance = prevention' of harm to them/herself in her mind? (e.g. "if I avoid touching this, no-one in my family will come to harm")
-Does she have 'rituals' - you mention washing anything the dog has touched, does she have others? (counting, touching something repeatedly)
-Does she have other related symptoms such as physical or verbal tics? hair pulling/skin picking/nail biting, hoarding, tourettes, etc.?
-Misophonia is sometimes associated with OCD/OCD-R conditions, it may be a spectrum condition but it isn't always present and it can alleviate.
You don't say how old she is, but if she can articulate what she specifically feels and the reasons for avoidance of things, note that in the diary, it helps to understand what the trigger is and why it triggers her and what she thinks about it (even if it is/seems irrational).
Try to tell her that the OCD is like a 'false friend' - the things it makes her do are not her fault. It makes her brain over-react to normal things. You and she knows she loves the dog. So when her brain tells her to avoid, it is just 'silly ocd' - a glitch in the brain that can be helped in different ways that you can try together.(it's important to encourage and not discourage hope - to help prepare her for engage with any future treatment you seek).
(5) Engage early with Exposure & Response Prevention (ERP) training:
This is a specialised form of Cognitive Behavioural Therapy that is first-line non-pharmacological treatment for OCD and has very good response rates in both adults and children. Some info here:
What is ERP: iocdf.org/about-ocd/treatment/erp/?_ga=2.134861426.2033691826.1726058603-1810442600.1726058603
https://kids.iocdf.org/professionals/mh/about-erp-for-pediatric-ocd/
Questions that parents might ask a therapist for EPR: https://kids.iocdf.org/for-parents/how-do-i-find-the-right-therapist/
Try to seek the advice of a therapist with specialty in ERP for Paediatric OCD to help introduce exposure and avoidance of compulsive-responses.
This leaflet is more geared towards adult ERP therapy for OCD but I put it here for some general information for you and anyone interested, and for the address at the bottom, to whom you could write for advice on ERP for Paediatric OCD, if you're in UK. They might be able to point you to some.

(6) The Dog
Your dog is going to be your best friend and ally for you and your daughter in helping her manage down the OCD symptoms through ERP.
Especially as you say: "She loves the dog as well, they were inseperable until recently, so I think dd would be devastated if she wasn't around any more, even with her struggling just now."
Therefore it appears that the OCD aversion to the sound and hair/drool of the dog is a very recent development, and the love your daughter has for her dog is going to be of great help in switching from aversion to acceptace and overcoming the compulsion to avoid her, if you can engage with ERP to help this.
While minimizing stressful situations (e.g. feeding dog in another room, keeping bedroom free of dog, etc.), it is important NOT to reaffirm OCD triggers with full avoidance - this compounds them. Getting rid of your much-loved dog is not the solution to OCD and your daughter does, as you rightly and intuitively say, need to learn strategies to deal with things and not have additional distress, burden of guilt and stress that would arise from getting rid of her beloved pet. It is important to note that the dog is not the only trigger. There are several.
Seek ERP help for dealing with this from a practiced therapist. In the meantime, get a book on it or have a look at online articles about it.
(7) Diet
I think food -relationship to development/exacerbation of OCD symptoms is something under investigation but not conclusive at the moment. However, foods that cause release of inflammatory agents in the body, or could result in dysbiosis, eg.overgrowth or imbalance of bacteria in the gut, may alter neurotransmitter synthesis, which in turn affects the brain and its structural development/activity/connectivity, might be involved at some level in symptom severity, even if not causal in condition development.
e.g. reducing sugar in diet might help decrease inflammatory agents in the body. With her doctor/specialist, perhaps review her dietary intake and see if you can reduce intake of overly sugary foods/ high GI foods and incorporate more whole-foods, omega 3 fats, vitamins B,C,D,E and Zinc, as they seem to be helpful in managing inflammatino as well as supporting neurotransmitter production. Also note in your diary, if her symptoms present or worsen after eating any particular foods.
(8) Vitamins
That is good that your daughter is on Vit D and B12 if she has been observed to be low in these vitamins. It's worth having her vitamin levels repeat tested when she has blood tests for her underlying conditions, and also asking her GP/specialist if she can receive elevated doses of Vit B12 and Vit D3 (if medically safe to do so) for a couple of months to see if symptoms of OCD decrease. (Vit B can also be given as an injection). The OTC supplements one takes daily take a while to work and might need higher levels over the recommended daily amount.
You could show the doc the meta-analysis paper I linked in my first reply to you above - there is good evidence for the role of Vit B (B12,B6 and other B vits) in regulating the levels of Homocysteine in the body. Elevated Homocysteine has implications for impaired production of neurostransmitters affecting the brain, involved in OCD and OCD-R.
Again, in the diary, note the doses and dates of consumption of the vitamins and note if the symptoms of OCD lessen over time.
(9) General reference info:
Contamination OCD:
Contamination OCD is a type of OCD which can present multiple triggers as an obsessive fear-aversion over-reaction and compulsions to avoid or mitigate those triggers. Triggers can change over time. It can take multiple forms per this overview:

OCD treatments overview:
This is a 2023 scientific review of current treatment modalities for OCD - pharmacological, non-pharmacological (such as ERP/CBT) and brain stimulation. I put it here for info for anyone interested.

These are the papers I linked previously. I am putting them here again so everything is in one place:

Try not to panic! You're doing very well with all that you are doing for your daughter, your dog,and reading up on OCD. Engage with OCD organisations, especially those for paediatric OCD, for advice on therapists for ERP and access to research.
Also, in all of the scientific papers, there is a correspondence address for the first author/multiple authors. Sometimes emailing them directly can open a gateway to further information or advice if clinical studies are ongoing/recruiting as that can be a pathway to treatment also.
Medicine is moving forward all the time and the day will come when these conditions can be managed well. The Vitamins B,C,D,E supplmentation and managing homocysteine levels is an interesting strategy.
Good wishes to you, to your daughter and dog!
